Seán Cullinane (born 1966) is a retired Irish hurler who formerly played with Passage at club level and with Waterford at inter-county level.
Seán was both Passage and Waterford's number one full back for the late 1990s and at the start of the 2000s. Seán's final match for Waterford came on 11 June 2001 against Limerick at Páirc Uí Chaoimh. Seán's inter-county career finished on a sour note, losing to Limerick by 3 points, after having led the match by 11 points after 16 minutes. Since Seán's retirement, it can be said that Waterford GAA have failed to successfully replace him at full back with a number of players such as Tom Feeney, Kevin Moran, Declan Prendergast and Ken McGrath all having been tried out at the position.
Seán had a frustrating club career with Passage having lost three Waterford Senior Hurling Championship finals, most notably in the 1993 final, having lost to Lismore GAA by a single point in an incredibly wet and windy day in Walsh Park. While Seán's final match for Waterford was a disappointment, his last match for Passage was more of a fairytale ending. At the age of 38, Seán came on as a sub in the 2007 Waterford Intermediate Hurling Championship final where Passage beat Dungarvan by 6 points. This ensured that Passage would be back playing senior hurling in 2008.
