William Selby (died c.1426)

William Selby (died c. 1426) was an English politician and merchant who served as the Member of Parliament for Rye on multiple occasions.

Selby's career is primarily documented through records of his parliamentary service. He represented Rye, a Cinque Port, in the Parliaments of 1413 (May), 1413 (November), 1414, 1415, and 1421 (May). Representation in Parliament for Cinque Ports was a significant role, often filled by individuals with mercantile or legal expertise, given the importance of maritime trade to the region.

His death is estimated to have occurred around 1426, based on the cessation of his activities in official records. Further details about his life, such as his occupation beyond being a merchant, his family, or specific contributions to Rye beyond his parliamentary representation, are currently scarce in available historical sources.
