Klein, Texas

Klein is an unincorporated community in Harris County, Texas, United States, roughly bordering SH 99 to the north, SH 249 to the west, I-45 to the east, and the city of Houston to the south. It includes the entire area of Klein ISD. Residents of the zip codes 77066, 77069, 77086, 77379, 77388, 77389 and 77391 can use Klein as their postal city. Klein is one of the most diverse, as well as being one of the largest unincorporated areas of Houston.

It is named after Adam Klein, a German immigrant whose best-known great-great-grandson is singer Lyle Lovett. Other famous sons and daughters of the Klein community include actor Jim Parsons, actor Lee Pace, actor Matthew Bomer, actress Lynn Collins, actress Sherry Stringfield, singer/songwriter Derek Webb, actor Ben Rappaport, Major League Baseball players David Murphy and Josh Barfield, NFL players Randy Bullock, Ashton Youboty, Mike Green, and Olympic gold medalists Laura Wilkinson, Simone Biles, and Chad Hedrick.

Klein is served by David Wayne Hooks Memorial Airport, one of just a few privately owned airports in the U.S. to have a Federal Aviation Administration control tower, and home to Civil Air Patrol's Delta Composite Squadron.

Klein has a Humid subtropical climate with a 9a Hardiness zone. The area is susceptible to hurricanes and flooding.

The area serves as a fringe ecocline boundary between the Piney Woods, southern post oak savanna, and prairie land as an extension of the Western Gulf coastal grasslands.

Much of the original ecosystem had been cleared for farming. Since then, the community has been rapidly built up by subdivisions, businesses, and mixed land use — and thus very little of the area represents its native ecosystem.

Most of the core Klein area sits between Spring Creek to the north, separating Tomball to the northwest by Willow Creek, and Cypress Creek is the waterway that passes through the center of the greater Klein area. Both these creeks are tributaries to lower Spring Creek (Harris County, Texas) and ultimately Lake Houston.

Parcels along Cypress Creek contain a mix of older undisturbed bottomland forest, private residence, and well-maintained bike trails through public parks.
