Prison Six (Hebrew: כלא שש Kele Shesh), officially Confinement Base 396 (Hebrew: בסיס כליאה 396 Bsis Kli'a 396) is an Israeli military prison located near Atlit, Israel, on Oren Junction.

Chief Military Police Officer Yosef Pressman pushed for its construction and it was finally built following the 1956 Sinai War.

On November 22, 1969 at about 21:00, Prison Six was flooded due to a powerful rainstorm, and the water level rose to a level of 2 m. The prison's security was compromised when the powerful water current destroyed the front gate and created holes in the outer walls.

[2] None of the prisoners used the flood as a means to escape, and instead helped in the effort to minimize the damage and prevent injury.

The agreement was immediately revoked and the leaders of the revolt received greater sentences.
