Association football is the most popular sport in Tuvalu. Football in Tuvalu is governed by the Tuvalu National Football Association (TNFA). The TNFA became an associate member association of the Oceania Football Confederation (OFC) on 15 November 2006 with a further reinstatement on 16 March 2020. The TNFA has been wanting to become a full member of the OFC and a member of FIFA since 1987.^[1]

The earliest records of football in Tuvalu date back to the 1979 South Pacific Games where Tuvalu competed. They defeated Tonga, but lost their other two matches. This qualified them for a play-off against Kiribati, which they would win on penalties before losing to Guam national football team. A league was active by 1980, with Nauti FC being founded in that year, and it would continue until 1991 when renovations prevented access to the airstrip for training or the Tuvalu Sports Ground for matches. It would reform in 1998 and has so far lasted to the current day. The women's league would form in 2009, though this would prove to be more sporadic and there is less evidence for it. In the modern era the men's league typically includes clubs from all the main islands, with A and B divisions, along with 2nd teams from the larger clubs. The women's league, in contrast, is much smaller, with only a handful of clubs participating. Typically the leagues are formatted as a group stage, either a single group of up to 8 teams or 2 separate groups of up to 4 teams. Then teams qualify for a semi-final and a final to determine the champions for that year.

Additionally, with league seasons being short, there are multiple competitions per year. In the modern era a typical year contains the league, the NBT Cup and at least one of a handful of other competitions such as: the Tuvalu Games (from 2008 to 2017),^[2] the Independence Cup (where teams compete under their island's name), the Christmas Cup and more. The ministry of education, youth and sports have also organised tournaments and a men's C-Division was formed in the 2022 NBT Cup for veteran's football. Otherwise the same clubs compete, though results can vary a little more.^[3][4] These tournaments are typically organised for both genders, though sometimes there have been insufficient teams for a women's division.

In international sport, they wouldn't return until the 2003 South Pacific Games, where a narrow 3–2 victory over Kiribati would prove to be their only victory from 4 matches. Otherwise they would lose 1–0 to Vanuatu and 4–0 to each the Solomon Islands and Fiji.

History was made in 2007 when Tuvalu became the first non FIFA member to participate in an official World Cup qualifying match.^[5] The situation arose when the regional governing body used the 2007 South Pacific Games, as the first stage of the qualification tournament for the 2010 FIFA World Cup and qualification tournament for the 2008 OFC Nations Cup. Tuvalu performed with great credit, earning a remarkable 1–1 draw with Tahiti in which Viliamu Sekifu became as the first World cup scorer for his country. The other three fixtures in the tournament ended in defeat and Tuvalu failed to progress from their five team group.

In September 2008, Tuvaluan Prime Minister Apisai Ielemia and the President of the Tuvalu Football Association, Tapugao Falefou, visited the headquarters of FIFA in Zürich, hoping to gain full membership in the organisation.^[1] However the lack of football facilities in Tuvalu is a major obstacle for membership of FIFA. Tuvalu only has one stadium, and it does not have training grounds or hotels for visiting teams and supporters.^[6][7][8]

In recent years the TNFA have received support from the Netherlands.^[9] In 2011 Foppe de Haan was the football coach of Tuvalu for the 2011 Pacific Games.^[10] They would perform well, but would not return for the 2015 edition. On 1 May 2012 Stevan de Geijter was appointed as the head of Youth Development at the TNFA.^[11] The Tuvalu national football team and the activities of the Dutch Support Tuvalu Foundation are the focus of Mission Tuvalu (Missie Tuvalu) (2013) a feature documentary directed by Jeroen van den Kroonenberg, in which the route for Tuvalu's FIFA membership is shown.

Football continues to strengthen on the islands to this day, with regular league action and international action including victories at the 2017 Pacific Mini Games, overseas action at the 2018 CONIFA World Football Cup and a further draw against full FIFA member American Samoa at the 2019 Pacific Games.

The number of participating clubs varies by tournament, with the larger islands often sending second or even third teams to compete. These typically play in the B-Division, though 2nd squads have played in the A-Division previously. Some clubs have only competed in the women's division. The main club is Nauti FC, who regularly win titles and compete across all divisions.
