The microSPARC (code-named "Tsunami") is a microprocessor implementing the SPARC V8 instruction set architecture (ISA) developed by Sun Microsystems. It was a low-end microprocessor intended for low-end workstations and embedded systems. The microprocessor was developed by Sun, but the floating-point unit (FPU) was licensed from Meiko Scientific. It contained 800,000 transistors.

There were two derivatives of the microSPARC: the microSPARC-II and microSPARC-IIep. The microSPARC-IIep was a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun. The microprocessor was used by Sun in their JavaStation Network Computer.
