Ypupiara (meaning “the one who lives in the water”) is an extinct genus of unenlagiine theropod from the Late Cretaceous Serra da Galga Formation of Brazil. It was the first member of the Dromaeosauridae to be discovered in South America and the first member of the Unenlagiinae to be discovered, but not the first to be identified as such. The type and only species, Y. lopai, is known solely from a specimen that was destroyed in a fire in 2018.
