Alimos War Cemetery, Commonwealth military memorial in Alimos, Greece.

Alimos War Cemetery is a memorial site in South Athens containing graves and monuments for Commonwealth soldiers who died during World War II. The grounds feature neat rows of white headstones arranged across well-maintained lawns, accessible from Poseidonos Avenue in the Alimos area.

The site first held Commonwealth soldiers killed between 1944 and 1946, during the Greek Civil War. The Greek state and the Commonwealth War Graves Commission then turned it into a cemetery for Commonwealth dead of World War II, gathering remains from battlefields, temporary military cemeteries and civilian graveyards across Greece. The architect was the British-Canadian Louis de Soissons, who designed many such cemeteries.

The cemetery is maintained by the Commonwealth War Graves Commission, and its graves and memorials record soldiers from Britain, Canada, Australia, New Zealand, India and other Commonwealth nations. A cremation memorial names 74 Indian soldiers, and a bilingual plaque marks the Crimean War plot moved here from the old Franco-British cemetery in 1966.

The cemetery faces Poseidonos Avenue at the mouth of the Pikrodafni stream, on the border of Alimos and Palaio Faliro, with the Alimos marina across the road on the sea side. The Crimean War plot with its bilingual "Franco British Cemetery - Crimean War" inscription lies in the north-eastern part of the grounds.

A separate section of the cemetery holds graves of soldiers and civilians who died in Greece after the Crimean War. These older burials show that the site has a longer history as a memorial and documents conflicts from different periods.
