Captain John Purves and His Wife, Eliza Anne Pritchard, is an oil-on-canvas portrait created by American painter Henry Benbridge (1743–1812).

A bequest from Henry Francis du Pont, the painting is held in the permanent collection of the Winterthur Museum, Garden and Library.

[2] Purves fought at Sullivan's Island and ended the war as lieutenant colonel of the Lower Ninety-Six District Regiment of Militia.

[3] Handed down through the Purveses' descendants to Eliza McKellar, this "vigorously painted double portrait" depicts the husband and wife in 1775 on the occasion of their marriage.

[2] Double portraits of husband and wife in the same frame, with no children or others present, are "surprisingly rare" in American colonial-era art.
