The Apella was the name of the popular assembly in the Ancient Greek city-state of Sparta. It was composed of free male Spartiates (Spartan citizens) over the age of 30. The apella was responsible for electing men to the gerousia for life. Candidates were selected from the aristocrats and presented before the apella. The candidate who received the loudest applause became a member of the gerousia.

The apella also elected the five ephors annually. Ephors presided over meetings of the gerousia and the apella. They could not run for re-election.

The gerousia presented motions before the apella. The apella then voted on the motions. However, unlike the ecclesia in Athens, the apella did not debate; it merely approved or disapproved of measures. Moreover, the gerousia always had the power to veto the decision of the apella.
