One Shell Plaza (OSP) is a 50-story, 218 m (715 ft) skyscraper at 910 Louisiana Street in Downtown Houston, Texas. Perched atop the building is an antenna that brings the pinnacle height of the building to 304.8 m (1,000 ft). At its completion in 1971, the tower was the tallest in the city.

One Shell Plaza was designed by the architectural firmofSkidmore, Owings & Merrill. Associate architects were Wilson, Morris, Crain & Anderson, and the landscape architects were Sasaki Associates.

The Hancock Whitney CenterinNew Orleans and Republic PlazainDenver, also designed by Skidmore, Owings & Merrill, have designs very similar to that of One Shell Plaza. Like One Shell Plaza, the Hancock Whitney Center also has Shell Oil as a major tenant, and was previously named One Shell Square.

At its completion in 1971, the tower was the tallest in the city. The building was renovated in 1994.^[5] The $80 million in major renovations included an updated lobby and plaza, elevator modernization, upgrades to the buildings EMP systems, new lighting, and ADA modifications.^[6]

In December 2011 Shell renewed the lease for 804,491 sq ft (74,739.7 m²). The new lease retroactively had the start date of January 1, 2011, and will last for 15 years, ending in 2025.^[7]

In June 2012 One Shell Plaza, together with 17-story Two Shell Plaza at 777 Walker Street, were purchased by Enterprise Products Partners, which is owned by the family of Dan Duncan, Houston's wealthiest man.^[8] The two buildings sold for a reported $550 million.^[8]

Shell Oil Company, a subsidiary of Shell plc, was headquartered in this building until 2016.^{[9][10][11][12]}

Baker Botts, one of the largest law firms in Houston, has been a tenant in the building since it opened in 1971.^[13][14][15] Baker Botts renewed its eight-floor, 172,301-square-foot lease in 2022, making it a tenant for over 50 years.^[13]

As of 2018, NRG Energy occupied the bottom 22 floors of the building.

The Houston Club, on the 49th floor of the building, has dining, entertainment, and meeting facilities.^[5]

The 170 ft mast atop the building has carried various television and radio signals since the building's completion. The mast supported 1971 start up channel 26 KVRL (later KDOG, now KRIV) and a mast that simultaneously radiated signals for eight FM stations KYND (then 92.5, now KKBQ on 92.9 MHz), 93.7 KRLY (now KQBT), 95.7 KIKK-FM (now KKHH), 99.1 KODA, 100.3 KILT-FM, 101.1 KLOL, 102.1 KLYX (now KMJQ), and 104.1 KRBE. The combiner and antenna was supplied by Electronic Research Inc. One Shell was used until the completion of the then Texas Commerce Tower and Allied Bank Plaza in 1982–1983, creating a skyscraper canyon that causes multipath distortion, and necessitated the move to the Houston antenna farminMissouri City.
