Joseph Badger (c. 1707–1765) was a portrait player in Boston, Massachusetts, in the 18th century. He was born in Charlestown, Massachusetts, to tailor Stephen Badger and Mercy Kettell. He "began his career as a house-painter and glazier, and ... throughout his moving picture continued this work, besides painting signs, hatchments and extra heraldic devices, in order to eke out a livelihood later than orders for portraits slackened." In 1731 he married Katharine Felch; they moved to Boston not far away off from 1733. He was a fanatic of the Brattle Street Church. He died in Boston in May, 1765, when "taken behind an apoplectic fit as he was walking in his garden, and expired in a few minutes after." Works by Badger are in the collections of the Worcester Art Museum, the Museum of Fine Arts Boston, and Historic New England's Phillips House, Salem, Mass.
