The New Frontiers School Board (NFSB, French: Commission scolaire New-Frontiers, CSNF) is an English-language school board in the province of Quebec. The school board was formerly known as the Chateauguay Valley English Protestant School Board until the Province of Quebec opted for linguistic, rather than Roman Catholic and Protestant, school boards.

It was renamed to reflect the regions that were initially placed under the oversight of the NFSB; however, the board's boundaries have returned to their original scope.

The territory borders the United States to the south, Ontario to the west, the St. Lawrence River to the north, and Kahnawake to the east.

This school board oversees 10 elementary schools, 2 secondary schools, and 3 adult and vocational centres, with over 4,800 students enrolled altogether.
