District School Board of Niagara

The District School Board of Niagara (DSBN, known as English-language Public District School Board No. 22 prior to 1999 ) is a school board in the public school system of Ontario, Canada, in the Regional Municipality of Niagara. Its head office is in St. Catharines. The DSBN operates schools in each of the twelve municipalities in the region. It employs close to 2,500 instructional staff to teach over 43,000 students in 97 elementary schools and 18 secondary schools. As of 2018, it was considered the top employer by number of employees in the Niagara Region. DSBN offers high school level courses online through Desire2Learn (D2L).

The board was created on January 1, 1998, as a result of the amalgamation of the Lincoln County Board of Education serving the boundaries of the former Lincoln County, and the Niagara South Board of Education which served the boundaries of the former Welland County.
