This list of tallest buildings in Indianapolis ranks skyscrapers and high-rises in the U.S. city of Indianapolis, Indiana, by height. The city's three skyscrapers and a majority of its high-rises are located in downtown Indianapolis. The tallest building in the city is the 49-story Salesforce Tower, which rises 701 ft, excluding antenna masts, and was completed in 1990. The structure is the tallest completed building in the state and the 175th tallest building in the U.S. The city's second tallest structure is the OneAmerica Tower, which was the tallest building in Indiana from 1982 until 1990. Of the 40 tallest buildings in Indiana, 34 are located in Indianapolis. The history of skyscrapers in Indianapolis began with the completion in 1895 of the Thomas Building, which is regarded as the first high-rise in the city. Before it was demolished, this structure stood 13 stories and 170 ft in height. Indianapolis went through an early high-rise construction boom in the 1960s, during which time the city saw the completion of the 372 ft City-County Building. The City-County Building was the first building in the city to rise higher than the Soldiers' and Sailors' Monument, and was the tallest building in the city until 1970. However, the pace of new high-rise construction then slowed until 1982; starting in that year, Indianapolis entered into a large building boom that lasted until 1990. During that time, six of the city's ten tallest skyscrapers were built, including the Chase Tower, OneAmerica Tower and Market Tower. Based on existing and under-construction buildings over 500 ft tall, the skyline of Indianapolis is ranked first in Indiana, sixth in the Midwest (after Chicago, Minneapolis, Detroit, Columbus and Cleveland) and 24th in the country. As of May 2014, there are 142 completed high-rises in the city. Indianapolis ranks first in the state in high-rise count, ahead of Fort Wayne. Indianapolis was the site of very little high-rise construction from the end of the boom in 1990 until the mid-2000s; the city has since entered into a third period of high-rise construction, with four skyscrapers that rank in city's 20 tallest buildings being completed after 2000. The tallest of these is the 376 ft JW Marriott Indianapolis, standing at 34 stories tall. Other projects completed after 2000 are the 287 ft Conrad Indianapolis and 259 ft Simon Property Group Headquarters, both in 2006. One Indiana Square, now known as Regions Tower, went through an exterior refinishing after being damaged by high winds on April 2, 2006. As of February 2019, there are four high-rise buildings under construction, approved for construction or proposed for construction in Indianapolis.

Timeline of tallest buildings

This lists buildings that once held the title of tallest building in Indianapolis.
