Calamba Claypot, also known as the Calamba Jar, is a landmark in Calamba, Laguna, Philippines believed to be the largest claypot in the world. It is located at the City Plaza near Calamba Church and Rizal Shrine. Built in 1937, it was constructed as a reference to the origin of the town's name from ''kalamba'', meaning "water jar". The giant claypot can also be found in the city's official seal. The plaza was proposed by the then town councilor Dr. Agapito Alzona, to utilize the area where the old town market once stood. The resolution was approved by the then town mayor Roman Lazaro. The giant claypot was built in 1937 and completed in 1939.
