Like the 70’s, the 1980’s was a very successful time for Llanfair Caereinion Football Club. In 1984, they won the Emrys Morgan Cup for the second time, beating Builth Wells in the final. In 1985 and 1986 they won back to back Montgomeryshire League titles and in 1986 they won the Emrys Morgan Cup again, this time beating Llanfyllin after a replay. Llanfair then did another back to back win when they lifted the Montgomeryshire League trophy in 1989 and 1990 taking the clubs still current total to 8 Amateur League Titles.
