Regency Tower, Residential high-rise in downtown Oklahoma City, United States

The Regency, at 333 Northwest 5th Street, is a 24-story residential building 238 feet tall with 274 apartments, from studios to three-bedroom units. Its pedestal holds a four-level parking garage on floors B and 1–3, with the lobby, concierge desk, leasing office and two retail spaces on floor 1. Floor 4 has the clubhouse, outdoor pool, fitness center and leasable offices; floors 6–24 are residential, most with balconies.

Construction of the building began in 1964 and finished in 1966, with its official opening coming in 1967 as a new residential addition to downtown Oklahoma City. The project reflected the city's economic growth and its modernization during that post-war period.

The building marks a shift in how Oklahoma City residents began living in the 1960s, moving away from single-family homes toward apartment living in tall structures. It shaped how people viewed urban living in the region during that era.

The building is at 333 Northwest 5th Street, in the northwest section of downtown Oklahoma City. Its pedestal holds a four-level parking garage with single and tandem spaces on floors B and 1–3. The lobby, with a concierge desk and leasing office, is on floor 1.

The structure survived the 1995 Oklahoma City bombing and underwent major restoration work in the months following the attack. Its recovery became a sign of the city's ability to rebuild and move forward after that tragedy.
