The Maitland Monument, also known as the Maitland Rotunda or the Peristyle of Maitland is a neoclassical monument located at the end of Spianada Square in Corfu. It was built in 1821 to honour Sir Thomas Maitland, a British military officer who was the last Civil Commissioner and first Lord High Commissioner of the Ionian Islands.

Maitland arrived in Corfu on 16 February 1816, and eight months later, on 25 October 1816, forty-six noble Corfiots made a proposal for the construction of a triumphal arch in his honour.

The monument is also known as the Cistern (Greek: Στέρνα), since it is built on top of a Venetian-era underground water cistern which had been built in 1781. The two entrances of the monument allowed access to the water tank.

The top of the monument contains the following circular inscription:

ΕΙΣ ΜΝΕΙΑΝ ΑΙΣΙΟΥ ΗΜΕΡΑΣ ΕΠΑΝΟΔΟΥ ΕΚ ΜΕΓΑΛΗΣ ΒΡΕΤΑΝΝΙΑΣ ΘΩΜΑ ΜΑΙΤΛΑΝΔΟΥ ΩΣ ΕΥΘΥΝΤΗΡΩΣ ΠΟΛΙΤΙΚΟΥ ΚΑΤΑΣΤΗΜΑΤΟΣ ΝΗΣΩΝ ΙΟΝΙΚΩΝ ΠΟΛΙΤΑΙ ΚΕΡΚΥΡΑΙΟΙ ΑΝΕΣΤΗΣΑΝ ΕΤΕΙ ΣΩΤ ΑΩΙΣΤ

The Maitland Monument is visible in the 1981 Bond film For Your Eyes Only.
