The Chiltonian League was an English football league, existing from 1984 until its merger with the Hellenic League in 2000. While never having a defined place in the English football league system, successful clubs moved from the Chiltonian League to the Combined Counties League and to the South Midlands League.
The league originally consisted of a single section of 17 clubs, most of which had previously competed in the Wycombe & District League.
After its inaugural season, the league expanded to two divisions (for first teams; reserve divisions were constituted separately). The divisions were originally known as Divisions One and Two, but after two seasons this was changed to Premier Division and Division One.
In 1995, the reserve divisions were scrapped and the league re-constituted into a single structure of three divisions - Premier Division, Division One and Division Two
With only six teams completing the 1998-99 Division Two season, that division was dropped and the league returned to a two-division structure. At the end of the 1999-00 season, the league merged into an expanded Hellenic League.
