Little Dark Age (abbreviated as LDA) is the fourth studio album by the American rock band MGMT, released on February 9, 2018, through Columbia Records. It was the band's first album of new material in over four years, after the release of their eponymous third studio album in September 2013.

After the band concluded touring at the end of 2014, members Andrew VanWyngarden and Benjamin Goldwasser took time off for most of 2015 before regrouping at the end of the year. The album was produced by the band with Patrick Wimberly and longtime collaborator Dave Fridmann. It features songwriting collaborations, a first for MGMT, with Wimberly, Ariel Pink and MGMT live band member James Richardson. It also features contributions from Sébastien Tellier and Connan Mockasin. Little Dark Age was preceded by the release of four singles: "Little Dark Age", "When You Die", "Hand It Over", and "Me and Michael".

The album received positive reviews from music critics, who saw it as a slight return to the pop style of the band's debut album, Oracular Spectacular. It peaked at #35 on the Billboard 200.
