The Isuzu Cubic (kana:いすゞ・キュービック) was a heavy-duty single-decker bus built by Isuzu between 1984 and 2000.

The various models of the vehicle were primarily available as a city bus configuration, either a complete bus or a bus chassis.

The Two-step and One-step versions were considered as step-entrance buses, whereas the Non-step version was considered as low-floor buses.
