Clarke Dermody (born 22 April 1980, in Invercargill) is a former New Zealand rugby union player who has gone on to coach professionally.

Dermody was born in Invercargill, New Zealand, and attended Southland Boys' High School. Dermody's great great grandfather Graham Shannon played for New Zealand in 1893.

Dermody played as a prop. He represented Woodlands in the Invercargill premier competition and was the second Woodlands player to have played for the All Blacks after Jimmy Cowan (All Black number 1046). They were later joined by Jamie Mackintosh (All Black 1081).

Dermody played 44 games for the Highlanders in Super Rugby and 89 games for Southland in the National Provincial Championship and Air New Zealand Cup.

In both matches he was substituted by Neemia Tialata after 67 minutes. He was not required in the 30-man squad for the 2006 Tri Nations Series. In November he played in another test, coming on to replace Tony Woodcock in the final 10 minutes of a 41-20 victory over England at Twickenham.

Dermody missed out on selection for the All Blacks in 2007 but was named in the Junior All Blacks for the Pacific Nations Cup. In November 2007 Dermody played his first of over 100 games in the London Irish jersey. He retired due to a back injury in 2012.^[2]
