Kolax, son of Amar, was a Klingon warrior that lived in the mid-24th century. He married Talij, and had a son, Kohlar. He died some time prior to 2377.

Like his father, and his father before him, Kolax was the commanding officer of a D-7-class battle cruiser that was crewed by a religious sect that was searching for the kuvah'magh.

Kohlar said a daily Plea for the Dead to honor Kolax in Sto-vo-kor. (VOY: "Prophecy")
