Woodstock Union High School (WUHS) is a mid-sized public secondary school located in Woodstock, Vermont, United States. As a member of the Mountain Views Supervisory Union (formerly the Windsor Central Unified Union School District), the school serves seven towns: Barnard, Bridgewater, Killington, Plymouth, Pomfret, Reading, and Woodstock. In addition, WUHS receives tuition students from other surrounding towns such as Hartland, Ludlow, Pittsfield, Sharon, Stockbridge, and Weathersfield, among others. The institution is accredited by the New England Association of Schools and Colleges. Woodstock serves approximately 385 High School students and 190 Middle School students in grades 8 and 7.

Woodstock's first public high school opened January 16, 1854. This opening was less than a year after the town, at its annual meeting, had voted to build the school. The land, purchased in April 1853, was on a knoll below Linden Hill. The current high school, built in 1957, sits on approximately 40 acres (16 ha) of land along the Ottauquechee River just west of the village of West Woodstock on U.S. Route 4. In 2023 school and community members proposed that.a new school building be built. Woodstock Union High School is consistently recognized for its educational quality and in 2020 was listed by U.S. News & World Report as the third best school in the state.

The high school has 10 academic departments including computer science, CRAFT, English, mathematics, modern & classical languages, music, science, social studies, visual and performing arts, and wellness. The interdisciplinary CRAFT program was introduced in 2023 to provide students with an ability to focus on environmental and sustainability themes. Classes in the program include foundations of agriculture, and economics and the environment.

There are Advanced Placement classes in subjects including art history, calculus, chemistry, computer science, government & politics, history, literature, and languages. In 2023 the school offered 16 AP courses. In 2018 the school opened a new Innovation Studio dedicated to "navigating the messiness of the creative process, from inception to completion," according to the 2018-2019 curriculum guide. In the studio in the fall of 2018, students partnered with peers in Turkey to design a playground. Teachers at Woodstock partner with staff at NuVu Innovation School in Cambridge, Mass., to operate the NuVu studio.
