Toms River High School North is a four-year comprehensive public high school, and was the second public high school established in Toms River, in Ocean County, New Jersey, United States, operating as part of the Toms River Regional Schools. The school opened in 1969 when the original high school (now called Toms River High School South) was found to be too small to accommodate the fast-growing community. However, the first class to graduate wasn't until 1971, since all of the seniors were kept at TRHSS for the class of 1970. Toms River High School North is the largest of all schools in the Toms River Regional School district. The TRHSN mascot is the Mariner, and the school colors are navy blue and gold. The other high schools in the district are Toms River High School East and Toms River High School South. The school day lasts six hours and 20 minutes.
