Annita Demetriou is a Cypriot politician, who serves as President of the Cypriot House of Representatives since June 2021, and as the President of the Democratic Rally (DISY) since March 2023. The latter role effectively designates her as the Leader of Opposition to the incumbent Christodoulides government.

The House of Representatives is the national unicameral legislature of the Republic of Cyprus. Members and three observers representing Armenian, Latin, and Maronite Cypriots are elected by proportional representation every five years. 30% of seats are allocated to Turkish Cypriots, but these have been vacant since 1964. The House of Representatives of Cyprus is the only legislature in Europe within a fully presidential system.
