Celtic have confirmed the date and kick-off time for the Scottish Cup semi-final against St Mirren. The match will take place at Hampden Park at 2pm on Sunday, April 19.
The fixture sets up another big afternoon at the national stadium for Martin O’Neill’s side. Celtic reached the last four after a tense quarter-final against Rangers at Ibrox. The match ended goalless after 120 minutes before Celtic held their nerve in the penalty shootout.

That result kept Celtic on course for the trophy, but the semi-final also brings a familiar opponent. St Mirren already faced Celtic in a major final earlier this season when the Paisley side defeated the Hoops in the League Cup final.
The stadium asks different questions compared with league matches. The pitch feels wider and the occasion carries its own tension. Players need patience in possession, while defenders must deal with long periods where the ball moves quickly between both boxes.

Celtic’s squad has plenty of experience in that environment. Several players have already played in finals and semi-finals at Hampden. That familiarity helps when matches tighten late on and decisions must be made quickly.
St Mirren will arrive believing they can repeat their earlier success. Their League Cup win showed they are capable of staying organised and taking chances when they appear.
St Mirren may arrive at Hampden in a period of change. Manager Stephen Robinson recently left the club to take the Aberdeen job, which means the Paisley side could approach the semi-final under an interim manager unless a permanent replacement is appointed before April.
The squad remains largely the same, but a managerial shift can affect preparation during a run toward a major cup tie.
For Celtic, the approach will centre on controlling the game. When they move the ball sharply through midfield, spaces begin to open. Wide areas also become important when opponents defend deep.

The April date also lands during the final stretch of the Premiership season. League fixtures around the split will sit either side of the semi-final, which means the squad must handle both competitions at once.
Supporters now have a clear date in the calendar. Hampden awaits again, with Celtic chasing a place in the Scottish Cup final and the chance to settle an earlier score with St Mirren.
