Rajabai Clock Tower is a landmark tower located in the Fort area of Mumbai, India. The tower stands at a height of 85 meters and was built in the late 19th century, between 1869 and 1878. The tower was designed by Sir George Gilbert Scott, a British architect who was also responsible for designing several other notable buildings in India, including the St. Mary's Church in Chennai.

The Rajabai Clock Tower is a combination of Gothic and Venetian styles of architecture. The tower is built using yellow Kurla stone and has a spiral staircase leading up to the top. The clock on the tower was made by a famous clockmaker, Benson, and is one of the few mechanical clocks in the world that plays tunes every quarter of an hour.

The tower was built by Sir David Sassoon, a prominent businessman and philanthropist, in memory of his mother, Rajabai. It is located within the University of Mumbai campus and is one of the most recognizable landmarks in the city. The tower is also home to the University of Mumbai's library, which is one of the oldest and largest libraries in the country.
