One America Plaza is an office tower at 600 West Broadway in San Diego, designed by Helmut Jahn of Murphy/Jahn with KMA Architecture. It was completed in 1991. The article gives no start date or materials and describes it only as an obelisk-shaped tower.

The tower has 34 stories and a roof height of 500 feet (150 m), with 623,001 square feet (57,879 square meters). Its height is capped by FAA limits because San Diego International Airport is nearby. The top is said to resemble the tip of a Phillips screwdriver. It holds the ground-floor America Plaza trolley station and Mitsubishi Electric elevators reported as the fastest in San Diego.

The Irvine Company bought it in February 2006 for US$300 million. It reportedly sold the tower to Saca Development in November 2025 for US$120 million. The article gives no public hours.
