Joseph Badger was a portrait artist 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 life continued this work, besides painting signs, hatchments and other heraldic devices, in order to eke out a livelihood when orders for portraits slackened." In 1731 he married Katharine Felch; they moved to Boston around 1733. He was a member of the Brattle Street Church. He died in Boston on May 11, 1765, when "on Saturday last one Mr. Badger, of this Town, Painter, was taken with 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. While respected in his own time, subsequent scholars and connoisseurs largely overlooked Badger's significance until Lawrence Park wrote a book about him in 1918.
