Rangers and Celtic will meet in the Scottish Cup last 16 in what will be the fourth Old Firm derby of the term.
Steven Gerrard’s champions welcome their Old Firm rivals – who have won the last four finals – on the weekend of 17/18 April and will do so again in the Premiership two weeks later.
Whoever prevails would host either St Johnstone or Clyde in the last eight.
Aberdeen will entertain Livingston in the only confirmed all-Premiership tie of the fourth round.
But each of the quarter-finals could be between top-flight teams, with Hibernian v Motherwell, Kilmarnock v St Mirren, and Aberdeen v Dundee United all potential match-ups should they win their respective ties.
All of the matches will be decided on the day, with extra time or penalties if needed.
Last 16 draw: Stranraer v Queen of the South or Hibernian; Motherwell v Greenock Morton; St Mirren v Inverness Caledonian Thistle; St Johnstone v Clyde; Rangers v Celtic; Aberdeen v Livingston; Forfar Athletic v Dundee United; Kilmarnock v Montrose.
Quarter-final draw: Rangers/Celtic v St Johnstone/Clyde; Kilmarnock/Montrose v St Mirren/Inverness Caledonian Thistle; Aberdeen/Livingston v Forfar Athletic/Dundee United; Stranraer/Queen of the South/Hibernian v Motherwell/Greenock Morton.
