Batu Caves is a limestone hill, which has a series of caves and cave temples, located in Gombak district, 13 kilometres (8.1 mi) north of Kuala Lumpur, Malaysia. It takes its name from the Sungai Batu or Batu River, which flows past the hill. Batu Caves is also the name of the nearby village.

The cave is one of the most popular Hindu shrines outside India, dedicated to Lord Murugan. It is the focal point of Hindu festival of Thaipusam in Malaysia which attracts over 1.5 million pilgrims yearly, making it one of the largest annual gatherings anywhere in the world.

Rising almost 100 m above the ground, Batu Caves temple complex consists of three main caves and a few smaller ones. The biggest, referred to as Cathedral Cave or Temple Cave, has a 100 m-high ceiling, and features ornate Hindu shrines. To reach it, visitors have to climb a steep flight of 272 steps. At the base of the hill are two more cave temples, Art Gallery Cave and Museum Cave, both of which are full of Hindu statues and paintings.
