In algebraic geometry, a White surface is one of the rational surfaces in Pⁿ studied by White (1923), generalizing cubic surfaces and Bordiga surfaces, which are the cases n = 3 or 4.

A White surface in Pⁿ is given by the embedding of P² blown up in n(n + 1)/2 points by the linear system of degree n curves through these points.
