Emerson Avenue Addition Historic District, Residential historic district in east Indianapolis, United States.

The Emerson Avenue Addition Historic District is a residential neighborhood in east Indianapolis with around 1,000 buildings spread across 143 acres. The structures include more than 650 houses and over 330 garages arranged along grid streets to form planned neighborhoods.

The district grew between about 1910 and 1949 as a planned residential section of Indianapolis, laid out under the names Emerson Heights Addition and Charles M. Cross Trust Clifford Avenue Addition. Its houses show Tudor Revival, Colonial Revival and Bungalow/American Craftsman styles. It was listed on the National Register of Historic Places in 2012.

Skilled workers, teachers, and journalists made their homes here and built close-knit neighborhoods in this early suburban development. Their houses reflect the pride of middle-class families establishing themselves in growing Indianapolis.

The district lies about 5 miles east of downtown Indianapolis, within the bounds of Emerson Avenue, Linwood Avenue, East 10th Street and East Michigan Street. The streets are residential and can be walked on foot; the houses, garages and architectural details are best seen from the public sidewalks.

The district's 1,000 contributing buildings and 9 contributing objects were recorded together when the area was listed on the National Register of Historic Places in 2012. The listing covers a planned residential section that took shape over nearly four decades, from about 1910 to 1949.
