St. Bernard's School is a private, all-male elementary school in the Carnegie Hill neighborhood of Manhattan's Upper East Side. It was founded in 1904 by John Card Jenkins, along with Francis Tabor. The school shield depicts an eagle (representing the United States of America), a lion (representing Great Britain), a book (symbol of education), and a cross (representing a tradition of Christianity).

The school's name is not pronounced the same way as that of the breed of dog with the same spelling, which is also its mascot. It was named for the rue St-Bernard in Brussels, Belgium, where a relative of one of St. Bernard's founders had also founded a school.
