John Stark Regional High School is a coeducational regional public high school in Weare, New Hampshire serving the communities of Weare and Henniker, New Hampshire.

John Stark Regional High School was created to serve the communities of Weare and Henniker, and was built in 1987 with the support of both towns.

After years of overcrowding, a $5 million addition/renovation project was approved by the voters of Weare and Henniker on March 14, 2000, but the project was delayed due to a legal challenge to "Senate Bill 2," which allowed towns to pass building projects with an approval of sixty percent of balloted votes versus the two-thirds majority of those towns using the town meeting form of government.

Fall sports include Bass Fishing, Cross Country, Field Hockey, Football, Golf, Soccer, and Volleyball.
