The 2013–14 British and Irish Cup was the fifth season of the annual rugby union competition for second tier, semi-professional clubs from Britain and Ireland.

Leinster A were the defending champions having won the 2012–13 Final with a 78th minute penalty by Noel Reid to beat Newcastle Falcons 18–17 at their home ground Kingston Park.

The format of the competition has been changed once again, with Welsh participation being reduced to just four teams (down from 12 in the previous season).

The Welsh teams were selected based on regional play-offs involving the 2013–14 Premier Division clubs at the start of the season.
