The National Center for Supercomputing Applications (NCSA) is a state-federal partnership to develop and deploy national-scale cyberinfrastructure that advances science and engineering. NCSA operates as a unit of the University of Illinois at Urbana-Champaign but it provides high-performance computing resources to researchers across the country. Support for NCSA comes from the National Science Foundation, the state of Illinois, the University of Illinois, business and industry partners, and other federal agencies.

These centers were founded when a group of University of Illinois faculty, led by Larry Smarr, sent an unsolicited proposal to the National Science Foundation in 1983. The foundation announced funding for the supercomputer centers in 1985; the first supercomputer at NCSA came online in January 1986.

NCSA provides leading-edge computing, data storage, and visualization resources. NCSA computational and data environment implements a multi-architecture hardware strategy, deploying both clusters and shared memory systems to support high-end users and communities on the architectures best-suited to their requirements. Nearly 1,360 scientists, engineers and students used the computing and data systems at NCSA to support research in more than 830 projects. A list of NCSA hardware is available at NCSA Capabilities
