HyTelnet (sometimes rendered Hytelnet or HYTELNET) was an early attempt to create a universal or at least simpler interface for the various Telnet-based information resources available before the World Wide Web. It was first developed in 1990 by Peter Scott, then at the University of Saskatchewan in Saskatoon, Canada. Using a client written by Earl Fogel, HyTelnet offered its users a primitive terminal-based GUI that allowed them to browse a directory of Telnet-based resources and then access them in a relatively standardized manner. On-line help was available, and there were frequent updates made available to its database which sites could download.

HyTelnet's chief inadequacy was that it was not centralized, i.e., every HyTelnet installation used its own separate copy of the master directory. While beneficial early-on, as it ensured no dependence on a central server, HyTelnet's user experience could vary widely as local installations might not have the same version of the client or might have obsolete information. This became a greater liability as more institutions had reliable, "always-on" Internet access. Finally, when the World Wide Web gained pre-eminence, many of the services that HyTelnet pointed to were gradually retired, increasingly limiting its relevance. HyTelnet's final database update was in 1997.
