In computer architecture, 48-bit integers, memory addresses, or other data units are those that are 48 bits (6 octets) wide. Also, 48-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.

The IBM AS/400, in its CISC variants, is a 48-bit system.
