Darren Cave (born 5 April 1987) is a retired professional Irish rugby union player who played centre for Ulster, sharing the province's appearance record with Andrew Trimble and Rob Herring with 229, and won eleven caps for Ireland.

[10] In 2010–11 Cave struggled with injuries but returned towards the end of the season and scored some vital tries as Ulster reached the quarter-finals of the Heineken Cup and semi-finals of the Magners League.

Cave showed excellent form on his return to action but picked up another injury in early 2012, just as he looked likely to be included in Ireland's Six Nations squad.

[11] In the 2012–13 campaign, Cave was ever-present as Ulster reached the final of the PRO12 and recorded a series of notable firsts including winning in France and beating every Welsh region in Wales.

Cave scored five tries the following season and was a stand-out player for the province as Ulster won all six of their Heineken Cup Pool matches and reached the PRO12 Play Off.
