Cypress is an unincorporated community in Harris County, Texas, United States, located completely inside the extraterritorial jurisdiction of the City of Houston.

The recent find of a San Patrice projectile point at the Dimond Knoll site nearby on Cypress Creek attests to a human presence in the area by 7500 BC.

By the early historic era, the area around present-day Cypress was populated by Atakapa and Akokisa Indian tribes, but they soon disappeared after the appearance of German settlers in the 1840s.

[2] The German heritage is most notably reflected in the names of some of the major thoroughfares of the area, such as Huffmeister and Telge Roads.

[4] The area remained mostly rural until the early 1990s when developers began construction of several master-planned communities.

[3] In March 2008, the Cypress Historical Society (CHS) was formed as a non-profit corporation with its primary mission being "...to discover, educate, promote, collect, preserve and make available to the public, historical documents and artifacts of the Cypress area".

[5] The CHS organization holds regular events aimed at exposing Cypress' residents to the historical and cultural foundation upon which the area was built.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters.

[13][14] Construction of Houston Methodist Cypress Hospital is currently under way on the former Texas Instruments/Compaq/Hewlett-Packard, Sysco campus, scheduled to open first quarter of 2025.

In 2023, OpenDoor.com named Cypress (77433) as the #1 hottest Zip Code for home buyers in the United States.
