Riho Terras (born 17 April 1967) is an Estonian politician and a former military officer who is serving as a member of the European Parliament since 1 February 2020.

In his youth, Terras was conscripted as a sailor in the Soviet Navy, serving with the Northern Fleet on the frigate Zadornyy.

He joined Johannes Kert in the defence of radio and television buildings in Tallinn during the 1991 Soviet coup d'état attempt.

Due to a lack of personnel in the Defence League, he decided to join a course for reserve officers, where he studied alongside Leo Kunnas.

In 1994 he started studying at the Bundeswehr University Munich, where he received a master's degree in Political Science and Sociology.

Before taking up the position of the Permanent Secretary, he was Deputy Chief of Staff for Operations in the Estonian Defence Forces.
