HAL Computer Systems, commonly just HAL, was an American fabless semiconductor company. Founded in 1990 with the goal of creating the world's fastest and most reliable 64-bit workstations, HAL is known for having designed one of first commercial 64-bit microprocessors.

HAL was founded in May 1990 by Andrew Heller, a highly regarded computer designer from IBM. HAL is named after HAL 9000, the AI computer in Arthur C. Clarke's Space Odyssey series. Failing to secure additional necessary funding, HAL secured $40 million from Fujitsu in exchange for 44% stake in late 1991.
