Ogros was a swampy planet in the Tau Ceti system. Ogros' swamps were filled with amino acids and proteins, which the native silicon-based Ogri absorbed for food. The Fourth Doctor had a very low opinion of Ogros.

Cessair of Diplos took three Ogri from Ogros, which contravened Article 7594 of the Galactic Charter. They were returned after sentence was passed upon her. (TV: The Stones of Blood)
