Niamh Cosgrave (born 9 October 1964) is a former Fine Gael politician from Dublin, Ireland. She campaigned for victims of the Hepatitis C blood contamination scandal, and was the subject of a book on this. She was briefly a member of the second house of the Irish parliament, and, for several years, of Dublin City Council, which, in a very rare move, removed her for non-attendance. She later moved to France, where she survived a serious attack; she was subsequently the subject of a TV documentary.
