Greater New Bedford Regional Vocational Technical High School is a public, four-year vocational technical high school for young men and women. With an enrollment of more than 2,000 students, GNB Voc-Tech is one of the largest vocational-technical high schools in Massachusetts. It serves the communities of New Bedford, Dartmouth and Fairhaven, Massachusetts.

The school's roots date back nearly a century, to the creation of the New Bedford Independent Industrial School in 1908. When it opened in 1909, the school served only 59 students, all from New Bedford. Over the years, the school built a reputation for excellence by providing quality vocational and academic programs. In 1918, its name was changed to New Bedford Vocational School. In 1946, it became New Bedford Vocational High School. In 1955, it became the first vocational high school to be accredited by the New England Association of Schools and Colleges.

In 1972, voters in New Bedford, Dartmouth and Fairhaven approved the establishment of a regional vocational school district and construction of a regional vocational school. In 1977, Greater New Bedford Regional Vocational Technical High School was opened.

Today, the school sits on a beautiful 48-acre campus in the North End of New Bedford, Massachusetts.

A $22 million addition and renovation project was completed in the fall of 2004. The project added new labs and classrooms and expanded the facilities for several career and technical programs, including Early Childhood Education and Teaching, Culinary Arts, Automotive Technology, Diesel Service Technology, and Plumbing and Pipe Fitting.
