Seán Crowe (born 7 March 1957) is an Irish Sinn Féin politician who has been a Teachta Dála (TD) for the Dublin South-West constituency since the 2011 general election, and previously from 2002 to 2007.

He worked as a community activist in the area, campaigning on such issues as the local hospital, transport, drugs and affordable housing.

During the 1990s, when the current Northern Ireland peace process was initiated, Crowe was the head of the Sinn Féin mission to the Forum for Peace and Reconciliation at Dublin Castle and was a member of Sinn Féin negotiating team.

Crowe has represented the party in the multi-party negotiations that led up to the Good Friday Agreement in 1998.

In September 2008, he returned to South Dublin County Council when he was co-opted to replace a party colleague and retained the seat at the 2009 local elections.
