Chhatrapati Shivaji Maharaj Vastu Sangrahalaya, originally named Prince of Wales Museum of Western India, is a museum in Bombay (Mumbai) which documents the history of India from prehistoric to modern times.

It was founded in the early years of the 20th century by prominent citizens of Mumbai, with the help of the government, to commemorate the visit of George V, who was Prince of Wales at the time. It is located in the heart of South Mumbai near the Gateway of India. The museum was renamed in 1998 after Shivaji, the founder of the Maratha Empire.

The building is built in the Indo-Saracenic style of architecture, incorporating elements of other styles of architecture like the Mughal, Maratha and Jain. The museum building is surrounded by a garden of palm trees and formal flower beds.

The museum houses approximately 50,000 exhibits of ancient Indian history as well as objects from foreign lands, categorised primarily into three sections: Art, Archaeology and Natural History. The museum houses Indus Valley Civilization artefacts, and other relics from ancient India from the time of the Guptas, Mauryas, Chalukyas and Rashtrakuta.
