Townsend Harris High School offers a wide range of extracurricular activities spanning the humanities, cultural societies, STEM, pre-professional clubs, and community service organizations. These student-led groups are typically organized with faculty advisors and provide opportunities for students to engage in academic interests, cultural exchange, leadership, and volunteer work outside the classroom. Two of the school’s most prominent annual extracurricular traditions are
SING! and the Festival of Nations (FON). SING! is a student theater competition in which students are divided into two teams: Freshiors (freshmen and juniors) and Semores (sophomores and seniors). Each team produces an original musical performance built around a central theme, such as escapism or historical adventures, incorporating acting, choreography, set design, and music. The Festival of Nations (FON) is a cultural performance that highlights the diversity of the school’s student body. Students organize and perform dances representing different cultural traditions, with the event serving as a celebration of the various cultural backgrounds represented within the school community. ==Student body==
