The Jamestown supply missions were a series of fleets from 1607 to around 1611 that were dispatched from England by the London Company with the specific goal of initially establishing the company's presence and later specifically maintaining the English settlement of "James Fort" on present-day Jamestown Island. The supply missions also resulted in the colonization of Bermuda as a supply and way-point between the colony and England.

The London Company, officially known as the Virginia Company of London, was a division of the Virginia Company with responsibility for colonizing the east coast of North America between latitudes 34° and 41° N.
