Arnold de Lantins (fl. 1420s – before 2 July 1432) was a Netherlandish composer of the late medieval and early Renaissance eras. He is one of a few composers who shows aspects of both medieval and Renaissance style, and was a contemporary of Dufay during Dufay's sojourn in Italy. He also wrote secular music, including ballades and rondeaux, all of which are in French, as well as a few shorter sacred pieces. Some of them refer to specific events or specific people, but none of either have been conclusively identified.
