The 1998–99 FA Cup was the 118th season of the FA Cup. The title defenders were Arsenal, who were eliminated in a semi-final replay by eventual winners Manchester United, who beat Newcastle United 2–0 in the final at the old Wembley Stadium. The goals were scored by Teddy Sheringham after 11 minutes, less than two minutes after coming on as a substitute for Roy Keane, and Paul Scholes on 53 minutes. It was the second leg of a historic treble for Manchester United; having already won the Premier League title the previous weekend, they went on to win the Champions League the following Wednesday.
