The National Solidarity Party (Spanish: Partido Solidaridad Nacional, PSN) was a political party in Guatemala.
In the general election held on 9 November 2003, the party was part of the Grand National Alliance (GANA).
In the legislative election, GANA won 24.3% of the vote, and 47 out of 158 seats in Congress.
In November 2005, following the withdrawal of the other two member parties from GANA, the PSN ceded its registration as a political party to the Grand National Alliance.
