Trast Athletic Club was a Cypriot football club, which currently does not exist. The club was a founding member of the Cyprus Football Association. The first Cypriot Championship and first Cyprus Cup were organized in 1934/35 and Trast AC was the first Champion of both competitions and became Double Winners. In the cup final of 1934/35, Trast AC beat APOEL FC 1-0 in the replay final. The first leg was 0-0.
They were cup winners in 1935/36 for the second consecutive time, when they beat LTSK 4-1, but were beaten in the final the following season by APOEL Nicosia, with the game ending 2-1. After one year break, Trast won the cup for third time in 1938, when they beat AE Limassol FC 2-1 in the final.
Despite the cups, the first championship trophy that was won by Trast was the only Championship trophy for the team. Until 1938 the team used to be in the second position, under the shadow of APOEL, which was constantly champion that period.
In 1938 the first Cypriot Champions folded.
