Teams from the
Football League First and
Second Division entered in this round. The third round of games in the FA Cup were intended to be played on 6 January 1979, but only four games were actually played on this date. Twenty more ties were played midweek over 8–10 January with a few more taking place on 15–16 and one on 18 January. Replays were intended for 9–10 January but again took place at various times. One tie, between Wrexham and Stockport County, suffered six postponements before finally being played on 1 February, by which time Arsenal and Sheffield Wednesday had played five times, the tie needing a fourth replay before being settled.
Maidstone United and
Altrincham were the last non-league clubs left in the competition. • During the 1-1 draw between Charlton Athletic and Maidstone United, referee Brian Martin sent off Charlton players
Mike Flanagan and
Derek Hales for fighting each other. • Shortly after Norwich City's 3-0 loss to Leicester, manager
John Bond transfer-listed three players -
John Ryan,
Graham Paddon and
Martin Chivers. ==Fourth round proper==
