The Herzliya Hebrew Gymnasium (Hebrew: הַגִּימְנַסְיָה הָעִבְרִית הֶרְצְלִיָּה, romanized: HaGimnasya Haivrit Herzliya, also known as Gymnasia Herzliya), originally known as HaGymnasia HaIvrit (lit. Hebrew High School) is a historic high school in Tel Aviv, Israel.

Gymnasia Herzliya was the country's first Hebrew high school, founded in 1905 in Jaffa, part of the Ottoman Empire in those days. The cornerstone-laying for the school's new building on Herzl Street in the Ahuzat Bayit neighborhood (the nucleus of future Tel Aviv) took place on July 28, 1909. The building was designed by Joseph Barsky, inspired by descriptions of Solomon's Temple.

The building on Herzl Street was a major Tel Aviv landmark until 1962, when the site was razed for the construction of Shalom Meir Tower. The new tower was the tallest building in Israel those days, representing a significant architectural achievement.

The destruction of the Hebrew High School building sparked widespread recognition of the importance of conserving historical landmarks. The Council for Conservation of Heritage Sites in Israel was founded in the 1980s partly in response to the fate of Herzliya Hebrew High School.

Located today on Jabotinsky Street, it serves as a six-year secondary school. The modern campus is entered through a gate that is reminiscent of the facade of the 1909 building.

Former principals include Haim Bograshov, Baruch Ben Yehuda and Carmi Yogev. In 1992, former Air Force fighter pilot and Brigadier General Ron Huldai was appointed principal. He implemented many changes and modernizations later adopted by other schools. After leaving the school, he was elected mayor of Tel Aviv. The current principal is Ze'ev Dgannie.
