The 1978–79 FA Cup was the 98th staging of the world's oldest football knockout competition, The Football Association Challenge Cup, or FA Cup. The final saw Arsenal beat Manchester United 3–2, three of the five goals being scored in the last five minutes.
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..
The fourth round of games were intended to be played over the weekend 26–27 January 1979, but by this time only eight matches had been played, of which three went to replays. The other games were completed either midweek on 29–31st, or on 5 or 12 February. Replays were played at various times after the initial games.
The sixth round of FA Cup games were played on 10 March 1979, except for the Southampton–Arsenal match which began on 19 March. Holders Ipswich Town were eliminated by Liverpool. There were three replays.
The right to show FA Cup games were, as with Football League matches, shared between the BBC and ITV network. All games were shown in a highlights format, except the Final, which was shown live both on BBC1 & ITV. The BBC football highlights programme Match of the Day would show up to three games and the various ITV regional network stations would cover up to one game and show highlights from other games covered elsewhere on the ITV network. No games from Rounds 1 or 2 were shown. Occasional highlights of replays would be shown on either the BBC or ITV.[1][2][3][4][5][6][7][8]
