Thomas Badger (1792–1868) was an artist in Boston, Massachusetts, in the 19th-century. He specialized in portraits. He trained with John Ritto Penniman. Portrait subjects included: John Abbot; William Allen, of Bowdoin College; Asa Clapp; Julia Margaretta Dearborn; George B. Doane; Henry Wadsworth Longfellow; Benjamin Page; Thomas Paul, of Boston’s African Meeting House; Jotham Sewall; Benjamin Vaughan; Charles Vaughan; Frances Western Apthorp Vaughan; George Wadsworth Wells; Jonathan Winship. Around 1849 a still life by Badger in the collection of the Boston Museum was considered “a highly finished and excellent picture, something in the style of Van Huysom. There is a truth and reality in the articles represented, seldom seen in this class of pictures.”
Works by Badger are in the collections of the Boston Athenaeum; Maine Historical Society; Colby College; the Brick Store Museum and Fine Arts Museums of San Francisco.
