Sendai Daikannon (仙台大観音), officially known as the Sendai Tendou Byakue Daikannon (仙台天道白衣大観音), is a large statue located in Sendai, Japan. It portrays a woman, the bodhisattva Byakue Kannon (白衣観音, "White-robed Kannon") bearing the cintamani gem (如意宝珠, Nyoihōju) in her hand.

It is the tallest statue of a goddess in Japan and as of 2023 is the eighth-tallest statue in the world at 100 metres (330 ft). The monument itself is 92 m (302 ft) tall, while the pedestal brings its total height to 100 m (330 ft). At the time of its completion in 1991, it was the tallest statue in the world, but was surpassed by Ushiku Daibutsu in 1993.

There is a small entry fee to enter the statue itself. Inside on the first floor are many large statues of Buddha and mythical kings. Visitors take an elevator to the 12th level then walk down the stairs and ramps to the ground. At each level there are eight Buddhas displayed in timber cabinets, 108 in total.
