The Clare Junior A Football Championship (abbreviated to Clare J<small>A</small>FC) is an annual GAA club competition organised by the Clare County Board for gaelic football clubs below intermediate and senior level. It is contested by the top-ranking junior gaelic football clubs in County Clare, Ireland. It is the third-tier adult competition of the Clare football pyramid.
The Clare J<small>A</small>FC was introduced in 1922 as a county-wide competition for gaelic football clubs deemed not strong enough for senior level. Intermediate level was introduced in 1927 for the same reason and placed above the Clare J<small>A</small>FC in the Clare football pyramid. In later years the Clare J<small>A</small>FC was opened to the second-, third-, and/or fourth-string teams from higher-ranked clubs.
The winners of the Clare J<small>A</small>FC are presented with the Michael Toner Cup, and are promoted to the Clare Intermediate Football Championship.
The current (2025) champions are Killimer who defeated Lissycasey by 0-17 to 1-13, to win their first title since 2023, and second overall at this grade.
The winners of the Clare J<small>A</small>FC also qualify to represent Clare in the Munster Junior Club Football Championship. However, if a second-, third-, or fourth-string team wins the Clare J<small>A</small>FC, the highest finishing first-string team qualifies instead.
Three Clare clubs have reached the Munster junior club final:
No Clare club has progressed to the All-Ireland Junior Club Football Championship.
