Theodor Evertz (fl. c. 1554) was a Franco-Flemish composer from the Renaissance.
Little is known about Evertz.
Three of his Dutch songs are preserved in the anthology of Dutch songs,, published by Jacob Bathen in Maastricht in 1554:
No complete set of parts of Jacob Bathen's anthology has yet been retrieved (the soprano voice is missing), but one of the songs for four voices has been published in Petrus Phalesius's in 1572, of which at least one complete copy has survived.
