The microSPARC (code-named Tsunami) is a discontinued microprocessor implementing the SPARC V8 instruction set architecture (ISA), developed by Sun Microsystems. It is 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 contains 800,000 transistors. It was used in the SPARCclassic and SPARCstation LX among others.

There are two variants of the microSPARC-II (code-named Swift): the microSPARC-II and microSPARC-IIep. The microSPARC-II is used in the SPARCstation 5. The microSPARC-IIep is a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun, and used in their JavaStation Network Computer.
