Who plays the character Charles Boyle?

Joe Lo Truglio plays Detective Charles Boyle in Brooklyn Nine-Nine. Charles is Jake Peralta's best friend and a detective at the 99th Precinct, known for his intense loyalty, unusual enthusiasm, and willingness to support Jake's investigations.

Lo Truglio's performance makes Boyle both a skilled police officer and one of the show's most eccentric comic characters. Charles is passionate about food, obscure hobbies, and workplace friendships, and he frequently expresses admiration for Jake in ways that are far more enthusiastic than Jake expects. Despite his quirks, Boyle is observant, brave, and highly committed to solving cases.

Charles's personal story grows across the series. He marries Genevieve Mirren-Carter, an art-gallery owner, and later helps raise their adopted son, Nikolaj. His close friendship with Jake remains a major emotional thread, even after Jake's relationship with Amy changes the precinct's social dynamics.

Joe Lo Truglio is also known for roles in films and television including Superbad, Wet Hot American Summer, and Reno 911!. In the series, he is distinct from Adam Scott, Rob Riggle, and Ken Marino, none of whom plays Charles Boyle.
