The IDS Center is an office skyscraper located at 80 South 8th Street in Minneapolis, Minnesota. Completed in 1973, it is the tallest building in Minneapolis, and the tallest building in the state at a height of 792 feet (241 m). It originally stood 775 feet 6 inches (236.37 m), though a 16-foot (4.9 m) garage for window washing equipment was added between 1978 and 1979. The structure rises to 910 feet (10,900 in) when including communications spires on the roof, indisputably the highest points in the city. The IDS was constructed as the headquarters of Investors Diversified Services, Inc.—now Ameriprise Financial. It also housed the headquarters of Dayton Hudson Corporation (now Target Corporation) from 1972 until 2001.

The complex consists of five parts: the 57-story IDS Tower itself at 8th Street & Nicollet Mall, an eight-story annex building along Marquette Avenue, the 19-story Marquette Hotel at 7th Street & Marquette Avenue, and a two-story retail building that was originally dominated by Woolworth's. These four buildings are joined by the seven-story Crystal Court.

The 57-story IDS became the tallest skyscraper in Minneapolis when it surpassed the height of the 32-story Foshay Tower in 1972, ending that building's 43-year reign over the city skyline. Construction of the building was followed with great interest, and the topping-off ceremony was a major civic event in the city. In addition to being taller, IDS occupies a much larger footprint than the obelisk-like Foshay. It was the 16th tallest building in the world on completion, and the third tallest constructed that year.
