Treniota (also spelled Troniata; Belarusian: Транята, romanized: Traniata; c. 1210 – 1264) was Grand Duke of Lithuania from 1263 to 1264.

[1] While Mindaugas had converted to Christianity in order to discourage Livonian Order and Teutonic Knights attacks on Lithuania, becoming king in the process, Treniota remained a staunch pagan.

Despite Mindaugas's conversion, the Teutonic Knights regularly made incursions in Lithuanian territory.

However, before he was able act against his pagan nephew, Treniota together with Daumantas assassinated Mindaugas and two of his sons in 1263.

However, he only ruled for a year before being deposed by Vaišvilkas, the younger son of Mindaugas.
