Tower 333 is a 20-story high-rise office building in the central business district of Bellevue, Washington, United States.

[needs update] In October 1997, local developer Eugene Horbach proposed the design of the Bellevue Technology Tower as a 19-story building with 350,000 sq ft (33,000 m2) of space.

To save the property from foreclosure in September 2002, Horbach sold a 10-acre (4 ha) development site he had spent 17 years acquiring.
