Dawn Purvis (born 1967) was an Independent Unionist member of the Northern Ireland Assembly. She was previously the leader of the Progressive Unionist Party (PUP) until she resigned in 2010. She lost her seat in the Assembly in the 2011 election.

Born in the Donegall Pass area of Belfast, Purvis joined the PUP in 1994. She stood for the party in the 1996 Northern Ireland Forum election in Belfast South and then in the 1998 Northern Ireland Assembly election in Belfast East, here taking only 271 votes.

By 1999, Purvis was the PUP's Spokesperson on Women's Affairs. She took a degree in Women's Studies, Social Policy and Social Anthropology and began working full time for the party.

Purvis stood in Belfast South in the 2001 UK general election, finishing in sixth place with a total of 1112 votes (2.9%).

In 2006, Purvis was appointed to the Northern Ireland Policing Board. Her appointment was later criticised by the Democratic Unionist Party, due to the PUP's links with the paramilitary Ulster Volunteer Force.
