Renaissance Square is a high-rise complex located in downtown Phoenix, Arizona. The complex includes two towers: One Renaissance Square at 347 ft (106 m) with 26 floors, and Two Renaissance Square at 372 ft (113 m) with 28 floors. Although a part of the same complex, Tower 1 was completed in 1986 while Tower 2 was completed in 1990. Renaissance Square, which is composed of buildings which stand as the seventh- and fourteenth-tallest buildings in Phoenix, is entirely an office complex. The two towers are connected by a skyway positioned halfway up the structures.

Developed by Trammell Crow Company, Renaissance Square was sold to the Pauls Corporation in 2005 for US$120 million. In late 2007, the Pauls Corporation sold the complex to the Hines U.S. Core Office Fund for US$273 million. It was the second-largest commercial exchange in Phoenix in 2007. In December, 2016 Oaktree Capital Management & Cypress Office Properties purchased the towers from Hines for US$150 million. In late 2017 the project underwent over US$50 million in building renovations. Cushman & Wakefield has the listing assignment to lease the project.
