Celtic went about their 2012-13 league campaign in a steady if not always inspiring manner.Motherwell, Inverness Caley Thistle and briefly Hibernian all either had spells at the top of the table, or thereabouts, but by Christmas Celtic had found a steady run of form to pull themselves comfortably clear of the pack. Celtic eventually clinched their 44th League title on 21 April 2013 with a 4–1 win over Inverness CT at Parkhead. Celtic's run in the League Cup saw them comfortably dispose of Raith Rovers (4–1) and St Johnstone (5–0) in the earlier rounds. St Mirren, however, pulled off an unexpected but deserved 3–2 win over Celtic in the semi-final.

Celtic's 2013 Scottish Cup campaign began inauspiciously with a home 1–1 draw against Second Division side, Arbroath. Celtic won the replay 1–0 with an Adam Matthews goal, but were again unconvincing. Celtic played Raith Rovers at Starks Park in the next round and eventually overcame a defensive performance by Raith to win 3–0, with Kris Commons, Charlie Mulgrew and James Forrest scoring the goals. In the quarter-finals, Celtic were drawn away to St Mirren, who had eliminated Celtic from the 2012–13 Scottish League Cup a month beforehand. Early goals by Joe Ledley and Anthony Stokes, either side of an equaliser by St Mirren, gave Celtic a 2–1 victory at St Mirren Park. In the semi-final at Hampden Park, Celtic won a thrilling match by 4–3 after extra time against Dundee United. A Kris Commons goal gave Celtic an early lead, but United scored twice midway through the first half to lead 2–1.Victor Wanyama scored an equaliser almost immediately and Commons scored another goal after 60 minutes to give Celtic a 3–2 lead.Jon Daly scored his second goal of the game to equalise and force extra time. Soon after Daly had hit the post, Anthony Stokes scored the winning goal.
