Green B. Trimble Technical High School (commonly known as Trimble Tech) is a Fort Worth Independent School District vocational high school on the south side of Fort Worth, Texas, United States, in the medical district.

Green B. Trimble Technical High School started in 1882 as Fort Worth High School. In 1910, the school's original building burned to the ground, forcing classes to move to elementary schools. The new Fort Worth High School building opened in 1911 on the corner of Jennings and Rosedale avenues in southwest Fort Worth. That building is now an apartment complex called Parker Commons.

In 1917, Bryce Building and Wyatt C. Hendrick Construction companies began construction on the building that now houses Trimble Tech. It was designed to resemble the original Fort Worth High School building that had been destroyed by fire.

Fort Worth High School was renamed Central High School in 1918, just after moving to its current location. The school proved popular among Fort Worth students, prompting an expansion that included an auditorium and gymnasium.

In 1935, Central High School was renamed after longtime principal R.L. Paschal, who retired that year after 29 years of service. R.L. Paschal High School still exists in the Fort Worth Independent School District, but it relocated in 1955 to the corner of Berry Street and Forest Park Boulevard, near Texas Christian University.

After the relocation of Paschal High School in 1955, the building was named Fort Worth Technical High School. The school saw a period of expansion during the next 12 years. In 1964, An increase in the size of the student body prompted the 1967 construction of a new academic wing on the east side of the building.

In 1967, the school was once again renamed, this time to Green B. Trimble Technical High School, upon the retirement of the principal who started the vocational aspect of the school. The school continued to expand. In 1972, a field house and athletic facilities were built on what was formerly Humbolt Street, south of the main building. A new gymnasium was added behind the main building in 1980. A 1998 bond referendum made it possible for Trimble Tech to add a new band hall, technology wing, cafeteria and library. The field house and athletic fields were also replaced.

Trimble Tech sits about two miles (3 km) south of downtown Fort Worth, in a district called the Near Southside. The 15-acre (61,000 m) campus is bound by West Cannon Street to the north, West Dashwood Street to the south, South Henderson Street to the west and College Avenue to the east.

The campus consists of the main building, an outside gymnasium and band hall and a field house. Outdoor athletic facilities include a running track, football practice field, tennis courts, a baseball field and a softball field.

Although Trimble Tech's enrollment varies from year to year, it generally maintains just under 2,000 students. It had 1,926 students during the 2007–2008 school year, of whom 76.2 percent were Hispanic, 20.6 percent were African American, 2.2 percent were white, 0.9 percent were Asian or Pacific Islanders and 0.1 percent were Native American.

Almost 70 percent of Trimble Tech's students were economically disadvantaged in the 2007–2008 school year, and 47 percent of them were considered at-risk.

Trimble Tech is a vocational school. In addition to Texas-mandated curriculum requirements, Tech's students take classes that prepare them for various technical and career fields, such as carpentry, auto repair and a special-interest program called health science and hospital administration.

In July 2010, Trimble Tech attained "Recognized" status based on its students' performance on state-mandated Texas Assessment of Knowledge and Skills standardized tests. The school was awarded the ACT College Readiness Award in 2010, 2011 and 2012.
