European Parliament elections were held in Greece on 13 June 1999 to elect the 25 Greek members to the European Parliament.

Members were elected by party-list proportional representation with a 3% threshold for any party.

The opposition conservative New Democracy party made gains as did the Communist Party of Greece, while the ruling PASOK lost ground.

Two parties on the left, the relatively new Democratic Social Movement and the Coalition of the Left and Progress elected two MEPs each.

Political Spring, which had elected 2 MEPs in 1994, was unsuccessful in passing the 3% threshold and did not elect any members.
