The Convent of the Order of Christ (Portuguese: Convento de Cristo) is a religious building and Roman Catholic building in Tomar, Portugal, originally a Templar stronghold built in the 12th century. After the Order of the Knights Templar was dissolved in the 14th century, the Portuguese branch of the order was turned into the Knights of the Order of Christ, which supported Portugal's maritime discoveries of the 15th century.

The Convent of Christ of Tomar is one of Portugal's most important historical and artistic monuments and has been in the World Heritage list of UNESCO since 1983.
