History Neptune High School was established in 1897 when the Ocean Grove Camp Meeting Association leased land at Main Street and Main Avenue in Ocean Grove to the Neptune Township Board of Education for educational purposes.DeMasters, Karen. "A Derelict School Gets New Life With the Arts", The New York Times, January 2, 2000. Accessed May 28, 2025. The original building, completed in 1898, was designed by local architect Ernest A. Arend, and it was notable for its distinctive Romanesque architecture."History of the Jersey Shore Arts Center", Jersey Shore Arts Center. Accessed May 28, 2025.

Lida Doren served as the school's first principal and superintendent, making her the first woman in New Jersey to hold both positions simultaneously at a public high school. The school received architectural acclaim, including an award at the 1906 World's Fair. The building served as the township’s main high school until the current facility opened on Neptune Boulevard in September 1960, and now exists as the Jersey Shore Arts Center.

The school’s mascot and nickname also carry historical significance. “Scarlet Fliers” was coined in 1928 by student journalist James Lawrence Ogle in reference to the basketball team’s red uniforms and fast-paced play. King Neptune became the school’s official symbol during the same period, representing strength and knowledge. Although a red-tailed hawk was briefly used as a mascot in the early 2000s, the King Neptune emblem was formally reinstated in 2005."History of King Neptune and the Scarlet Fliers", Neptune Township Clerk's Office.
