The Tevarin diaspora refers to the general movement of Tevarin in the centuries following their defeat in the First and Second Tevarin Wars.

Following the loss of their homeworld Kaleeth, renamed Jalan (Elysium IV), to the United Empire of Earth (UEE) in SEY 2546, the Tevarin that had not already fled the planet were forcefully removed from their homeworld and made to inhabit camps and resettlement communities established throughout the UEE. While many Tevarin were eventually integrated into Human society, others opted to distance themselves from the UEE and form isolated enclaves and communities in less settled areas of the known galaxy, such as the Tevarin settlement on Branaugh II.
