The 2014–15 British and Irish Cup is the sixth season of the annual rugby union competition for second tier, semi-professional clubs from Britain and Ireland. Leinster A are the defending champions having won the 2013–14 final against Yorkshire Carnegie 44–17 at Donnybrook on 23 May 2014. There has been four different winners and five different losing finalists of the competition in the five seasons of its existence.

The format of the competition has been changed once again, with the Scottish withdrawing from the competition because of an increase, from four to six, in the number of the group matches before Christmas. Scottish Rugby felt that Scottish teams would not be able to compete fully in both the British and Irish Cup and the Scottish Premiership, the top-flight league for clubs in Scotland. The Welsh teams selection is based on regional play-offs involving the 2013–14 Premier Division clubs at the start of the season. This process yielded Pontypridd to represent the Cardiff Blues Region, Cross Keys to represent the Dragons Region, Aberavon to represent the Ospreys Region, and Carmarthen Quins to represent the Scarlets Region.

Matches in the competition proper were played on the same weekends as the European Rugby Champions Cup and European Rugby Challenge Cup. First round matches began on 10 October 2014 and the final was held on 3 April 2015. Worcester Warriors beat Doncaster Knights 35 – 5 in the final held at Castle Park, Doncaster; the home ground of the Knights.
