In addition to their first team competing in the Scottish Championship, Hamilton Academical F.C. also maintain a reserve team competing in the SPFL Reserve League, as well as further teams for younger age groups playing in competitions such as the Scottish Challenge Cup and the Scottish Youth Cup within the club's academy. A reserve team was fielded for many years until the abandonment of the most recent league for those teams in 2009. An under-20 side took part in the SPFL Development League until it was disbanded in 2018.
