To Mega Therion is the second studio album by Swiss extreme metal band Celtic Frost, released in October 1985 through Noise Records. The cover artwork is a painting by H. R. Giger titled Satan I.

"To Mega Therion" translates to the great beast in Greek. It is an expression found in the Bible but was also a nickname used by Aleister Crowley.

The album was highly influential on death metal and black metal, and some consider it to be one of the best albums of the 1980s.
