Nicola Sinnott (born 8 August 1987) is a Republic of Ireland womens international footballer who plays for Wexford Youths of the Womens National League.
Sinnott made her international debut at under-17 level for Ireland in April 2004. She was named player of the tournament in a four-team competition hosted in Castlebar. She later played at under-19 level and represented Irish Universities at the World University Games, playing in the 2009 tournament in Belgrade.
In May 2015, Sinnott was called up to the senior national team for the first time, for a friendly in the United States. After the match had been arranged, it was discovered to be outside FIFAs designated dates for international matches, so several of Irelands first-choice players were not released by their clubs. Sinnott won a debut cap as a late substitute for Stephanie Roche in Irelands 3–0 defeat.]
