Ivassi township was a settlement in Bajor's Dahkur Province, near Hathon.

In the 2350s, Gul Morad Pirak ordered Bajorans in his area to display the Galor Banner. Fifteen farmers from Ivassi township did not, leading Pirak to order their execution. Ataan Rhukal oversaw the execution. (DS9 novel: Fearful Symmetry)

The incident was first mentioned in "The Darkness and the Light".
