The Grand Alliance for National Unity (GANA; Spanish: Gran Alianza por la Unidad Nacional) is a political party in El Salvador. The party established itself on 16 January 2010 and was recognized by the Supreme Electoral Court of El Salvador on 19 May of the same year.
The majority of party members came from the Nationalist Republican Alliance (ARENA). Originally the defection from ARENA included 12 deputies in the Legislative Assembly. There have been accusations of ARENA members being bought or blackmailed by the GANA party in order to secure them in their party. GANA has also been accused of multiple cases of corruption.
On 1 June 2019, Nayib Bukele under the banner of the GANA party became the first president of El Salvador since José Napoleón Duarte to come from outside of the two major political parties in El Salvador, the ARENA and FMLN. Bukele is also the first president to be elected while a part of GANA.
