Petter Stenborg (1719 – 6 November 1781) was a Swedish stage actor and theater director. He was the director of the Stenborg Company or Svenska Comoedi-truppen from 1758 onward and as such the director of the Humlegårdsteatern (1773–80) in Stockholm. Petter Stenborg played an important role in Swedish theater history: he was a member of the pioneer actors of the first Swedish national stage in Bollhuset, and as the leader of the Stenborg theatre company, one of only two professional Swedish language theater companies active in the mid 18th-century, he kept professional Swedish language theater alive from the closure of the public theater in Bollhuset in 1754, until the inauguration of the Royal Swedish Opera (1773) and Royal Dramatic Theatre (1788).
