Diarmuid Cloonan (born 1980) is an Irish hurler who played as a full-back for the Galway senior team.
He arrived on the inter-county scene at the age of seventeen when he first linked up with the Galway minor team, before later joining the under-21 side.
Cloonan went on to play a bit part for Galway for the next few years, and won one National Hurling League medal.

[citation needed] His brother, Eugene, also played at all levels with Galway, and is regarded as one of the county's greatest-ever forwards.
