Timoleon Vassos or Vasos (Greek: Τιμολέων Βάσσος or Βάσος; c. 1836–1929) was a Hellenic Army officer and general.

He was born in Athens in 1836, the younger son of the hero of the Greek Revolution Vasos Mavrovouniotis.

In February 1897, as a colonel, he was sent at the head of an expeditionary force to Crete to assist the local Cretan revolt against the Ottoman Empire, an act which precipitated the outbreak of the Greco-Turkish War of 1897.
