Leading seaman is a junior non-commissioned rank or rate in navies, particularly those of the Commonwealth. When it is used by NATO nations, leading seaman has the rank code of OR-4.

The rank is used in the navies of Australia, Bangladesh, Canada, Finland, Ghana, India, Ireland, Namibia, New Zealand, Norway, Pakistan, South Africa, Sri Lanka and the United Kingdom.
