Watterson Towers is a student residence hall at Illinois State University, and is said by the university to be one of the tallest dormitory buildings in the world^[1] at 298.5 feet. Located in Normal, Illinois, at the corner of Fell and Beaufort Streets, it was completed in 1969. The 28-story complex holds over 2,200 students and stands at 91m (298.5 feet),^{[citation needed]} making it one of the tallest brutalist structures in the world. Watterson Towers was named after Arthur W. Watterson, a popular professor and chair of the ISU Geography Department, who taught at the University from 1946–1966. The building was designed by Fridstein and Fitch Architects in Chicago, and built by C. Iber and Sons Company of Peoria, Illinois.

Externally, the most noticeable feature of the building is that it consists of two separate towers. From the outside an observer sees that the two towers are connected at several points by breezeways. However, to the residents, this division into towers goes almost unnoticed, as what is far more important is the internal division of the building into houses. Watterson is composed of ten of these houses, (five in each tower), and each is considered—in terms of campus governance—to be its own residence hall. The houses used to be named after the first ten secretaries of state of the United States. As of 2020 each house is now an alphabet letter. A house at the bottom, and E house at the top.

Each "house" consists of five consecutive floors of a tower. Houses at the same level are paired both physically (in terms of access, see below) and in terms of student governance. For example, the bottom five residential floors of the South Tower and the bottom five residential floors of the North Tower comprise "[A North/South] collectively.

Within each house, most floors are divided into four "suites" consisting of six rooms each. The suites include four double occupancy rooms, a triple room, and a single occupancy room. However, on the middle (third) floor of each house, there are only two suites, as the area for the other two suites is taken up by other things, including the connecting breezeways and some study lounges.

Watterson Towers is the tallest structure in Bloomington-Normal, and can be seen when entering the twin cities from either direction.

Watterson Towers, now more than 50 years old, experienced a complete restoration, which was completed using the houses as stages.^[2] The food court renovations were completed in 2010, and all work was completed by early 2013.^[3]
