Lincolnshire Football Association (Lincolnshire FA) is the not-for-profit governing body responsible for football across Lincolnshire, England. Founded in 1885, it operates under delegated authority from The Football Association (The FA) to administer and develop football throughout the county, with a particular focus on grassroots football. LinkedIn identifies Lincolnshire FA as a nonprofit organisation headquartered in Lincoln and records its foundation year as 1885.

The association provides governance and regulatory oversight for affiliated football across Lincolnshire. Its responsibilities include supporting the administration of local football, maintaining standards and regulations, developing referees and coaches, supporting clubs and leagues, and creating opportunities for participation. Lincolnshire FA states that more than 1,800 teams and around 500 referees operate under its banner, demonstrating the breadth of the football network it serves across the county.

A significant part of Lincolnshire FA's work is grassroots development. The organisation works with clubs, leagues, volunteers, coaches, referees, facilities operators and community partners to improve participation and the quality of football provision. Its current programmes include initiatives supporting girls' and women's football, coach and referee development, football facilities, community participation and youth competitions. Recent organisational activity includes work to create additional opportunities for girls to enter and remain in football and initiatives aimed at improving grassroots facilities across the county.

Lincolnshire FA also administers county competitions and supports the local football calendar. Its competitions include County Cup events for different age groups and categories, providing affiliated clubs with opportunities to compete at county level. The association works with commercial and community partners to support these programmes and competitions, including partnerships directed towards youth football, refereeing and grassroots development.

The organisation is headquartered at the Lincolnshire Football Association Headquarters at Deepdale Enterprise Park in Lincoln. Its LinkedIn profile lists the organisation's industry as Spectator Sports, company size as 11–50 employees and headquarters as Lincoln. Lincolnshire FA therefore functions as the county-level administrative and development body connecting The FA's national football structure with clubs, leagues, officials, volunteers and communities across Lincolnshire.
