Mysore (ⁱ/ˈmaɪsɔər/; Maisūru in Kannada) is the second-largest city in the state of Karnataka, India. Located at the base of the Chamundi Hills about 146 km (91 mi) southwest of the state capital Bangalore, it is spread across an area of 128.42 km² (50 sq mi). According to the provisional results of the 2011 national census of India, the population of Mysore is 887,446 and Hinduism is its major religion. Mysore City Corporation is responsible for the civic administration of the city, which is also the headquarters of the Mysore district and the Mysore division.

Until 1947, Mysore served as the capital of the Kingdom of Mysore. The kingdom was ruled by the Wodeyar dynasty, except for a brief period in the late 18th century when Hyder Ali and Tipu Sultan usurped power. Patrons of art and culture, the Wodeyars contributed significantly to the cultural growth of the city. The cultural ambience and achievements of Mysore earned it the sobriquet Cultural capital of Karnataka.

Mysore is noted for its palaces including the Mysore Palace, and the festivities that take place during the Dasara festival when the city receives a large number of tourists. It lends its name to the Mysore style of painting, the sweet dish Mysore Pak, the Mysore Peta (a traditional silk turban) and the garment known as the Mysore silk saree. Tourism is the major industry, while information technology has emerged as a major employer alongside the traditional industries. With no airport, Mysore depends on rail and bus transport for inter-city connections. The city was the location of the first private radio station in India. Mysore houses Mysore University which has produced several notable authors, particularly in the field of Kannada literature. Cricket is the most popular sport in the city.
