The New York Riptide were a professional box lacrosse franchise based in Uniondale, New York. They were members of the Eastern Conference of the National Lacrosse League (NLL) and played home games at Nassau Coliseum and began their first season in 2019.

2024 was the team's final season in Uniondale as the Riptide moved to Ottawa, with the team rebranding as the Ottawa Black Bears beginning with the 2024-2025 season.

On December 12, 2018, the NLL awarded an expansion franchise to Uniondale, New York and owner GF Sports. The team began play in December 2019 with its home arena being the Nassau Coliseum. The Riptide mark the return of the National Lacrosse League to the Long Island area after the departure of the New York Saints (1989–2003) and the New York Titans (2006–2009), both of whom also played at Nassau Coliseum.

The New York Riptide name and logo were announced on February 17, 2019, as chosen by fans.

On January 18, 2020, the Riptide got their first win in franchise history when they beat the Georgia Swarm by a score of 13–12 in overtime at Nassau Coliseum.

On June 3, 2020, the entire coaching staff and lacrosse operations team, including head coach and general manager Regy Thorpe, were fired.

On July 10, 2020, the Riptide announced the hiring of Jim Veltman as general manager and Dan Ladouceur as head coach.

Veltman was relieved of his duties on January 9, 2023, and replaced by executive vice president Rich Lisk.
