|Event||European Rugby Champions Cup Qualification Play-off|
|Date||23 and 30 May 2015|
The 2015–16 European Rugby Champions Cup-Challenge Cup play-off was the second play-off for entry into the top level competition of European Club rugby union, the European Rugby Champions Cup.
Following the two-team play-off in 2014–15, an expanded, four-team format was due to be used. However, on 24 September 2014, it was announced this would instead be a three-team play-off, with the highest placed non-qualifying team taking part.
To accommodate the longer season in the French Top 14, the format was announced as follows:
Gloucester became the first team to qualify for the play-off, taking the place allocated to the Premiership, when they beat Edinburgh 19–13 in the Challenge Cup final on 1 May 2015. This result meant that the 7th place team in the 2014–15 Premiership will no longer take part in the play-off, and will compete in the Challenge Cup. Connacht qualified next, when the finished seventh in the 2014–15 Pro12 with 50 points, narrowly edging Edinburgh who had 48 points. Bordeaux Bègles qualified for the play-off on 23 May 2015.
Connacht played Gloucester away at Gloucester's Kingsholm Stadium on Sunday 24 May 2015, with the venue having been decided earlier by a coin toss.< It was decided that, in the event of a Gloucester win, the second play-off match would be played at Sixways Stadium in Worcester, to avoid a clash of fixtures with a Madness concert.
