《名侦探柯南》（日语：名探侦コナン；官方英语：Detective Conan；北美发行商英译：Case Closed），是日本一部以侦探推理情节为主题的漫画作品，作者为青山刚昌。 原作漫画于1994年起开始在小学馆旗下杂志《周刊少年Sunday》上连载。自1994年以来，已一共发行了89卷单行本。在北美，由于考虑到法律上的限制，小学馆在北美的代理发行商Viz Media将名字翻译成了“Case Closed”。

Case Closed, also known as Detective Conan(名探侦コナン,Meitantei Konan), is a Japanese detective manga series written and illustrated by Gosho Aoyama. The series is serialized in Shogakukan's Weekly Shōnen Sunday since January 19, 1994, and has been collected into 89 tankōbon volumes. Due to legal considerations with the name Detective Conan, the English language release was renamed to Case Closed. The story follows Kudo Shinichi, an amateur detective who transformed into a child while investigating the Black Organization.
