Agia Anna (Greek: Αγία Άννα meaning Saint Anne) is a mountain village in the municipal unit of Oleni, Elis, Greece.

Agia Anna is built on the slopes of the hill Axofolia, a western spur of the Foloi plateau.

The village Agia Anna was founded in a remote place during Ottoman rule, to hide from the Turks.

Between 1841 and 1912, the community was part of the old municipality of Lampeia.

It was an independent community until 1997, when it became part of the municipality of Oleni under the Kapodistrias reform.
