'''SuperBASIC''' is an advanced variant of the [[BASIC programming language]] with many [[structured programming]] additions. It was developed at [[Sinclair Research]] by [[Jan Jones (novelist)|Jan Jones]] during the early 1980s. 

Originally SuperBASIC was intended as the [[BASIC interpreter]] for a [[home computer]] code-named ''SuperSpectrum'', then under development. This project was later cancelled; however, SuperBASIC was subsequently included in the [[read-only memory|ROM]] [[firmware]] of the [[Sinclair QL]] [[microcomputer]] (announced in January 1984), also serving as the [[command line interpreter]] for the QL's [[Sinclair QDOS|QDOS]] [[operating system]].<ref>{{Cite web |title=Illustrating Super-BASIC on the Sinclair QL |url=http://www.computinghistory.org.uk/det/12985/Illustrating-Super-BASIC-on-the-Sinclair-QL/ |access-date=2023-02-06 |website=Computing History}}</ref><ref>{{Cite web |last=Apostolo |first=Alberto |title=Sinclair QL: mistakes, misfortune and so many regrets |url=https://issuu.com/retromagazineworld/docs/retromagazine_00_eng/s/11179075 |access-date=2023-02-06 |website=RetroMagazineWorld |language=en}}</ref>

It was one of the first [[BASIC programming language#Structured BASIC|second-generation BASIC]]s to be integrated into a microcomputer's operating system (unlike [[BBC BASIC]] which preceded it in 1981), making the OS user-extendable—as done by [[Linus Torvalds#Early years|Linus Torvalds]] in his formative years.
