Crosby is a census-designated place in Harris County, Texas, United States.

[3] The site north of U.S. Route 90 (according to some) was an encampment nicknamed Lick Skillet in 1823 by Humphrey Jackson, one of the 300 original colonists to settle Texas.

"[citation needed] Humphrey Jackson (1784–1833)[5] moved to Texas from Louisiana in September 1823 and built a log cabin outside Austin's colony on the San Jacinto River, 0.5 miles (800 m) west of the site of present-day Crosby.

On August 16, 1824, the Baron de Bastrop granted him title to a league and a labor of land, including the place where he had settled, in what is now Harris County.

Jackson next petitioned the Mexican government to form the San Jacinto District under control of the Austin colony; he was elected alcalde of the new district in 1824, 1825, and 1827, and served as ex officio militia captain of the San Jacinto area.

[6] The first general store was built in 1865 by Charlie Karcher, and thereafter the town would become a shipping and retail center for lumber and agricultural products.

In 1877, the town was renamed by former judge, state representative, legislator, and Vice President of the railroad, Josiah Frasier Crosby, and a post office was established.

Maine, Rhode Island, Michigan, Kansas and Indiana are sending representatives, so the folks in Crosby decided they'de [sic] get into the act.

[12] According to the United States Census Bureau, the CDP has a total area of 2.3 square miles (6.0 km2), all land, which is located north of the historical Barrett Station.

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

[23] As of the 2020 United States census, there were 3,417 people, 1,026 households, and 579 families residing in the CDP.

[35] Crosby Volunteer Fire Department, funded by Harris County Emergency Services District #80, was formed in 1942.

The protection area is split into two response districts covered by five stations staffed entirely by volunteers from the community.

The Barrett Station/Riley Chambers Community Center is located at 808 Magnolia Ave. Facilities include restrooms, picnic, playground, trails, open shelter, basketball, baseball, riding arena, and football fields.

According to the Texas Education Agency AEIS report in 2007–2008, Crosby ISD served 4,855 students in ZIP code 77532.
