HSR Layout, an abbreviation of Hosur Sarjapura Road Layout, is a suburb in South Eastern Bangalore, India. The locality, initially developed by the Bangalore Development Authority in 1985, has now emerged as a residential area due to its proximity to Electronic City, Sarjapur Road and the Outer Ring Road on which I.T. Parks and other Special Economic Zones are located. It lies in the Bommanahalli constituency of the Karnataka State Assembly.

Neighbouring localities of Agara, Parangipalya, Venkatapura, Somsundarapalya, Mangammanapalya and Hosapalya are also part of HSR Layout.

Designed based on modern town planning principles, the layout has a centralized BDA Complex, which houses the city administrative offices and also other commercial establishments.

Other prominent areas like Koramangala and BTM Layout are also easily accessible. Parks and modern civic amenities are some of the best maintained in the area.

The area is built on land reclaimed from Agara lake, is located between Hosur Road and Sarjapur Road. HSR Layout is about 7km from Bangalore's other large residential area of Jayanagar, and 2km from Koramangala.

HSR Layout is divided into seven sectors which have main roads and cross roads. Main roads run north–south and Cross roads run east–west.

Agara lake is popular water body in HSR layout for morning walks and various activities.

HSR Layout is a home to several small and medium-sized parks which are actively maintained by BBMP. Few years ago, burning of dry leaves became a major problem here. By building a network of compost pits and getting BBMP on board, residents have put an end to the hazard of garbage.
