Hutchinson's incisors (also known as Hutchinson's teeth, Hutchinson's sign or Hutchinson-Boeck teeth) are a sign of congenital syphilis.

Babies with Hutchinson's incisors have teeth that are smaller, have notches on their biting surfaces, and are more widely spaced than normal.

Hutchinson's incisors is named after the English surgeon and pathologist, Sir Jonathan Hutchinson (1828-1913), who first described them.

Hutchinson's incisors form part of Hutchinson's triad.
