Tyvak Nano-Satellite Systems was an American company designing and building satellites. It started as a designer, builder and provider of nanosatellite and CubeSat space vehicle products and services for government and commercial customers. Tyvak was based in Irvine, California. It was a subsidiary of Terran Orbital Corporation. In 2022, it was announced that Tyvak would transition into larger satellites from nanosats and cubesats and the name Tyvak would be phased out in favor of the name of the parent company Terran Orbital.

In 2011, Jordi Puig-Suari, co-inventor of the CubeSat design, and Scott MacGillivray, former manager of nanosatellite programs for Boeing Phantom Works, established Tyvak Nano-Satellite Systems in San Luis Obispo, California, to sell miniature avionics packages for small satellites, with the goal to increase the volume available for payloads.

On 18 November 2019, Tyvak was one of five companies selected to be eligible to bid for the NASA Commercial Lunar Payload Services (CLPS).

In 2022, Terran Orbital company, the company that owns Tyvak, entered public stock market through a SPAC merger. At the time it was announced that the name Tyvak would be phased out and the focus of the whole company (that is, both Tyvak and Terran Orbital) would be transitioned into larger satellites from nanosats and cubesats.
