Detective Bureau 2-3: Go to Hell Bastards! (探偵事務所２３ くたばれ悪党ども, Tantei Jimusho 23: Kutabare Akutōdomo, aka Detective Bureau 23: Down with the Wicked) is a 1963 Japanese yakuza film directed by Seijun Suzuki in the vein of the Nikkatsu Studio's "borderless action cinema." It starred Joe Shishido as Hideo Tajima.

This was the first part of a series which ended after the second installment. That second film, Detective Bureau 2-3: A Man Weak to Money and Women, with Shishido returning as Hideo Tajima, was directed by Nozomu Yanase and released later the same year (1963).
