English: The Taj Mahal Palace Hotel is a heritage[1] five-star luxury hotel in the Colaba region of Mumbai, Maharashtra, India, situated next to the Gateway of India. Historically it was known as the "Taj Mahal Hotel"[2][3] or the "Taj Palace Hotel"[4] or simply "the Taj".

Part of the Taj Hotels Resorts and Palaces, this hotel is considered the flagship property of the group and contains 560 rooms and 44 suites. There are some 1,600 staff including 35 butlers. From a historical and architectural point of view, the two buildings that make up the hotel, the Taj Mahal Palace, and the Tower are two distinct buildings, built at different times and in different architectural designs. In 2017, the Taj Mahal Palace Hotel has acquired an image trademark.[5] It is the first building in the country to get intellectual property rights protection for its architectural design.[6][7]

The hotel has hosted many notable guests, from presidents to captains of industry and stars of show business.[8][9] Pakistan's founder, Muhammad Ali Jinnah's second wife Ratanbai Petit lived in the hotel during her last days in 1929—her mother, Sylla Tata, was born into the Tata family.[10]
