Christian Jacob Theophilus de Meza (November 26, 1756 – April 6, 1844) was a Danish physician and author.

De Meza was born in Copenhagen in 1756. He was the son of the physician Christian de Meza [de], with whom he embraced Christianity in 1783. In the same year he graduated as M.D. from the University of Copenhagen, and became a member of the Royal Medical Society.

From 1784 until his death he practised medicine in Elsinore.

Meza published essays in medical journals. He also wrote a drama, Dormon og Vilhelmine that was produced at the Royal Theatre, Copenhagen, in 1796.

Meza's son, Christian Julius de Meza (1792–1865), was a general in the Danish army during the Second Schleswig War.
