Comita II or III (died 1147) was the giudice (judge) of the Judicate of Arborea from 1131 until his death.

In 1130, Constantine, Gonario II of Torres, and Comita I of Gallura swore fealty to the archbishop of Pisa.

From 1133 to 1145, there is a gap in the testimony referring to Comita and it is possible that his brother Torbeno successfully usurped his throne during a war with the Judicate of Logudoro.

The Pisan prelate, travelling the island as a papal legate, had excommunicated the judge for oppressing the people and warring against Pisa.

Bernard of Clairvaux even weighed into island politics and sent a letter to Pope Eugene III to justify Baldwin's actions.
