Thadeus Origin and Meaning

The name Thadeus is a boy's name.

Thadeus is a masculine name with Greek origins, representing a variant spelling of Thaddeus, derived from the Aramaic term "thaddai" meaning "heart" or "courageous." The name appears in biblical tradition as one of Jesus's twelve apostles, sometimes identified as Jude. Throughout history, Thadeus has maintained steady but moderate usage, particularly in Eastern European countries and among families with Greek, Polish or Russian heritage. The spelling variation without the double 'd' gives it a slightly streamlined appearance while maintaining its classical roots. Thadeus conveys a sense of strength and dignity, offering the friendly nickname options of Thad or Tad.
