Giles Linnett Barrett (b. c. 1744 - d. 18 November 1809) was an English actor who came to the United States in the 1790s, and was most popular in Boston.
[5] He managed the Federal Street Theatre in Boston circa 1798 until it was destroyed by a fire in February 1798.
He briefly returned to managing the theater in 1799 after it was rebuilt, but the season was not a success.
[4] Barrett notes therein that Adams had seen him perform the role of General Warren in Bunker-Hill, a 1797 play by John Daly Burk, and was "induced to hope, my humble exertions may still Live in Your Memory.
"[4] When Adams had seen the play in New York and been asked his opinion afterward by Barrett, Adams replied "My friend, General Warren was a scholar and a gentleman, but your author has made him a bully and a blackguard."
