Wat Chedi Luang (Temple of the Big Stupa) is an impressive ruined temple in the center of Chiang Mai, northern Thailand, dating from the 14th and 15th centuries.

The Ruined Brick Chedi of Wat Chedi Luang now rises to about 60m in height. Its base is 44m (144 ft.) wide. It has four sides, each with a niche approached by a monumental stairway guarded by stone nagas (mythical snakes). Elephants stand guard midway up the platform.

Despite its ruined state, the chedi still has several Buddha shrines and remains an active place of worship frequented by saffron-robed monks.
