The Gateway School is an independent school on the Upper West Side of Manhattan serving children ages 5–14 with learning disabilities. It currently enrolls approximately 180 students.

Gateway students typically have difficulty in mainstream classrooms due to a language-based learning disability (dyslexia, expressive and receptive language delays, reading and writing disorders); attention deficit hyperactivity disorder; and/or executive function disorder.

The Gateway School of New York was established in 1965 by Elizabeth Freidus and Claire Flom. Freidus was an educator at Columbia University Teachers College; Claire Flom was the mother of Gateway's first student. The initial class consisted of five students in a space rented from Madison Avenue Presbyterian Church on Manhattan's Upper East Side. The school remained in this location for 36 years.

In 2001, Gateway moved into a converted brownstone at 236 Second Avenue near Union Square. With the decision to add a Middle School to the existing Lower School, Gateway began searching for an even larger building, and it debuted its current home on West 61st Street, near Lincoln Center, in 2008.

In the 2024-2025 school year, Gateway celebrated its 60th anniversary.
