Ila is an area of Trondheim, Norway, It is located in the western part of Midtbyen, the downtown area of Trondheim. Ila is bordered by the river Nidelva in the south, Skansen in the north and Steinberget, Bymarka and Ilsvikøra in the west. The area is mostly residential, with some industry and commerce. The Gråkallbanen tram line runs through Ila and the area is served by the Skansen Train Station on the Trønderbanen commuter train line. Nordre Avlastningsvei, which was completed during 2010, connects Ila via Brattøra to Lademoen. 
The first settlement at Ila was in the second half of the 18th century. During the 19th century, the area developed as the entertainment centre of Trondheim, with dance saloons, pubs and liquor store. In 1826 it was the site for the first Norwegian Constitution Day parade. During the late 19th century the area started being redeveloped into dense labour class housing, with a school opening in 1877. Ilen Church (Ila kirke) was opened in 1889 and in 1893 Ilalinjen, a horsecar line, was built with Ila Station as the terminus and rebuilt to a tramway in 1901.
