Aylesbury United were formed in 1897 as a merger of Night School, Printing Works and Aylesbury Town. After playing in local leagues, the club joined the Western Division of the
Spartan League in 1908, which they won in their first season. This was followed by a play-off with the winners of the Eastern Division,
Luton Clarence, which Aylesbury won 4–1. Further league reorganisation at the end of the season saw the creation of a Premier Division, in which Aylesbury were placed. However, after finishing bottom of the table in 1932–33 they were relegated to Division One. Two seasons later, a second-placed finish saw them promoted back to the Premier Division. The 1937–38 season saw the club relegated again, although they won Division One the following season. However, the league was then suspended due to
World War II. The league resumed in 1945 and was split into three geographic divisions, with Aylesbury in the Western Division, finishing as runners-up in 1945–46. Several clubs left the league at the end of the season, resulting in it being reduced to a single division. Although Aylesbury were relegated at the end of the
first season in the division, dropping into the
Isthmian League Premier Division, a 1–0 defeat of
Waterlooville saw them reach the second round of the FA Cup for the first time, where they lost 1–0 to
Sutton United. which was featured on the
BBC's ''
They Think It's All Over'' programme. In the same season they won the Isthmian League Cup. However, in
2009–10 they finished bottom of the division and were relegated to the Premier Division of the
Spartan South Midlands League. After finishing as runners-up in
2012–13, they were promoted to Division One Central of the Southern League.
