Born Diego Armando Maradona in 30 October 1960, in Lanús, Buenos Aires, Argentina.

He made his full international debut at age 16.

On 20 October 1976, Maradona made his professional debut for Argentinos Juniors, 10 days before his 16th birthday.

Maradona scored his first goal in the Primera División against Marplatense team San Lorenzo on 14 November 1976, two weeks after turning 16.

Maradona signed a contract with Boca Juniors on 20 February 1981.

After the 1982 World Cup, in June, Maradona was transferred to Barcelona in Spain for a then world record fee of £5 million ($7.6 million).

From the mid-1980s until 2004, Maradona was addicted to cocaine. He allegedly began using the drug in Barcelona in 1983.

The end of the 1983–84 season included a violent and chaotic fight Maradona was directly involved in at the 1984 Copa del Rey final at the Santiago Bernabéu in Madrid against Athletic Bilbao. After receiving another rough tackle by Goikoetxea which wounded his leg, being taunted with xenophobic, racist insults related to his father's Native American ancestry throughout the match by Bilbao fans, and being provoked by Bilbao's Miguel Sola at full time as Barcelona lost 1–0, Maradona snapped. The mass brawl was played out in front of the Spanish King Juan Carlos and an audience of 100,000 fans inside the stadium, and more than half of Spain watching on television.

Maradona transferred to Napoli in Italy's Serie A for another world record fee, £6.9 million ($10.48M). Maradona arrived in Naples and was presented to the world media as a Napoli player on 5 July 1984, where he was welcomed by 75,000 fans at his presentation at the Stadio San Paolo.

Maradona married long-time fiancée Claudia Villafañe on 7 November 1984 in Buenos Aires, and they had two daughters, Dalma Nerea (born 2 April 1987) and Gianinna Dinorah (born 16 May 1989), by whom he became a grandfather in 2009.

Argentina eliminated England at the Azteca Stadium, also in Mexico City. After scoring two contrasting goals in the 2–1 quarter-final win against England, his legend was cemented. The majesty of his second goal and the notoriety of his first led to the French newspaper L'Equipe describing Maradona as "half-angel, half-devil". This match was played with the background of the Falklands War between Argentina and the United Kingdom. Replays showed that the first goal was scored by striking the ball with his hand. Maradona was coyly evasive, describing it as "a little with the head of Maradona and a little with the hand of God". It became known as the "Hand of God". Maradona's second goal, just four minutes after the hotly disputed hand-goal, was later voted by FIFA as the greatest goal in the history of the World Cup. He received the ball in his own half, swiveled around and with 11 touches ran more than half the length of the field, dribbling past five English outfield players (Peter Beardsley, Steve Hodge, Peter Reid, Terry Butcher, and Terry Fenwick) before he left goalkeeper Peter Shilton on his backside with a feint, and slotted the ball into the net.

Maradona captained the Argentine national team to victory in the 1986 World Cup in Mexico, winning the final in Mexico City against West Germany.

During a meeting with Pope John Paul II at the Vatican in 1987, they clashed on the issue of wealth disparity, with Maradona stating, "I argued with him because I was in the Vatican and I saw all these golden ceilings and afterwards I heard the Pope say the Church was worried about the welfare of poor kids. Sell your ceiling then amigo, do something!".

Led by Maradona, Napoli won their first ever Serie A Italian Championship in 1986–87.

Maradona era in Napoli included the UEFA Cup in 1989. The 1989 UEFA Cup Final was a football tie played on 3 May 1989 and 17 May 1989 between S.S.C. Napoli of Italy and VfB Stuttgart of West Germany. Napoli won 5–4 on aggregate.

The 1990 FIFA World Cup Final was a football match played between West Germany and Argentina to determine the winner of the 1990 FIFA World Cup. The game took place on 8 July 1990 at the Stadio Olimpico in Italy's capital and largest city, Rome, and was won 1–0 by West Germany, with a late penalty kick taken by Andreas Brehme being the game's only goal.

In 1990, the Konex Foundation from Argentina granted him the Diamond Konex Award, one of the most prestigious culture awards in Argentina, as the most important personality in Sports in the last decade in his country.

Napoli would win their second league title in 1989–90, and finish runners up in the league twice, in 1987–88 and 1988–89.

By the time he was playing for Napoli, he had a full-blown addiction, which interfered with his ability to play football. In the midst of his drug crisis in 1991, Maradona was asked by journalists if the hit song Mi enfermedad (lit. My Disease) was dedicated to him.

After serving a 15-month ban for failing a drug test for cocaine, Maradona left Napoli in disgrace in 1992. Despite interest from Real Madrid and Marseille, he signed for Sevilla, where he stayed for one year.

In 1993, he played for Newell's Old Boys and in 1995 returned to Boca Juniors for a two-year stint.

At the 1994 World Cup in the United States, Maradona played in only two games (both at the Foxboro Stadium near Boston), scoring one goal against Greece, before being sent home after failing a drug test for ephedrine doping. After scoring against Greece, Maradona had one of the most infamous World Cup goal celebrations as he ran towards one of the sideline cameras shouting with a distorted face and bulging eyes. This turned out to be Maradona's last international goal for Argentina.

A 2–1 victory over Nigeria which was to be his last game for Argentina, he set-up both of his team's goals on free-kicks, the second an assist to Caniggia.

In April 1996, Maradona had a three-round exhibition boxing match with Santos Laciar for charity.

Maradona Retired. In 1996, he played in a friendly match alongside his brother Raul for Toronto Italia against the Canadian National Soccer League All-Stars. Maradona was himself given a testimonial match in November 2001, played between an all-star World XI and the Argentina national team.

In 2000, Maradona published his autobiography Yo Soy El Diego ("I am The Diego"), which became a best-seller in Argentina. Two years later, Maradona donated the Cuban royalties of his book to "the Cuban people and Fidel".

In 2001, the Argentine Football Association (AFA) asked FIFA for authorization to retire the jersey number 10 for Maradona. FIFA did not grant the request, even though Argentine officials have maintained that FIFA hinted that it would.

Maradona has topped a number of fan polls, including a 2002 FIFA poll in which his second goal against England was chosen as the best goal ever scored in a World Cup; he also won the most votes in a poll to determine the All-Time Ultimate World Cup Team.

Maradona admitted he is the father of Diego Sinagra (born in Naples on 20 September 1986). The Italian courts had already ruled so in 1993, after Maradona refused to undergo DNA tests to prove or disprove his paternity. Diego Junior met Maradona for the first time in May 2003 after tricking his way onto a golf course in Italy where Maradona was playing.

In 2003, Maradona was employed by the Libyan footballer Al-Saadi Gaddafi, the third son of Colonel Muammar Gaddafi, as a "technical consultant", while Al-Saadi was playing for the Italian club, Perugia, which was playing in Serie A at the time.

On 22 June 2005, it was announced that Maradona would return to former club Boca Juniors as a sports vice-president in charge of managing the First Division roster (after a disappointing 2004–05 season, which coincided with Boca's centenary). His contract began on 1 August 2005, and one of his first recommendations proved to be very effective: advising the club to hire Alfio Basile as the new coach. With Maradona fostering a close relationship with the players, Boca won the 2005 Apertura, the 2006 Clausura, the 2005 Copa Sudamericana, and the 2005 Recopa Sudamericana.

On 15 August 2005, Maradona made his debut as host of a talk-variety show on Argentine television, La Noche del 10 ("The Night of the no. 10"). His main guest on opening night was Pelé; the two had a friendly chat, showing no signs of past differences. However, the show also included a cartoon villain with a clear physical resemblance to Pelé. In subsequent evenings, he led the ratings on all occasions but one. Most guests were drawn from the worlds of football and show business, including Ronaldo and Zinedine Zidane, but also included interviews with other notable friends and personalities such as Cuban leader Fidel Castro and boxers Roberto Durán and Mike Tyson. Maradona gave each of his guests a signed Argentina jersey, which Tyson wore when he arrived in Brazil, Argentina's biggest rivals.

In November 2005, however, Maradona rejected an offer to work with Argentina's national football team.

In 2005, Maradona came to Venezuela to meet Chávez, who received him in the Miraflores Palace.

After winning his first three matches in charge of the national team, he oversaw a 6–1 defeat to Bolivia, equalling the team's worst-ever margin of defeat. With two matches remaining in the qualification tournament for the 2010 World Cup, Argentina was in fifth place and faced the possibility of failing to qualify, but victory in the last two matches secured qualification for the finals. After Argentina's qualification, Maradona used abusive language at the live post-game press conference, telling members of the media to "suck it and keep on sucking it". FIFA responded with a two-month ban on all footballing activity, which expired on 15 January 2010, and a CHF 25,000 fine, with a warning as to his future conduct.
