Clinton Hennessy (born 28 July 1977) is an Irish hurler who played as a goalkeeper for the Waterford senior team.
Hennessy joined the team when he replaced Stephen Brenner as first-choice 'keeper in 2005 and was a regular member of the starting fifteen until his retirement in 2012.
2008 began poorly for Waterford as the team lost their opening game to Clare as well as their manager Justin McCarthy.
In spite of this poor start Hennessy's side reached the All-Ireland final for the first time in forty-five years.
The game turned into a nightmare as the Tipperary forwards ran riot and put seven goals past Hennessy.
