RSI is a punk band formed in Christchurch, New Zealand, in 2000. The group releases a demo in 2001, then follows it with a self-titled album before relocating to Wellington. Its line-up includes Lance Guyatt on bass, Nathan Neumann on vocals and drums, Marcus Logan on guitar, and Jolan Kilkelly on guitar and vocals.

The name is also used by another act associated with Australian noise music, but the New Zealand punk band is the one described here.
