'''Squeak''' is an [[Object-oriented programming|object-oriented]], [[Class (computer programming)|class-based]], and [[Reflective programming|reflective]] [[programming language]]. It was derived from [[Smalltalk]]-80 by a group that included some of Smalltalk-80's original developers, initially at [[Apple Inc.|Apple Computer]], then at [[Walt Disney Imagineering]], where it was intended for use in internal Disney projects. The group later was supported by [[HP Labs]], [[SAP]], and most recently, [[Y Combinator]].

Squeak runs on a [[Stack machine|stack virtual machine]] (VM), allowing for a high degree of portability. The Squeak system includes code for generating a new version of the VM on which it runs, along with a VM simulator<ref name="miranda_2018">{{cite book |first1=Eliot |last1=Miranda |first2=Clément |last2=Béra |first3=Elisa |last3=Gonzalez Boix |first4=Dan |last4=Ingalls |year=2018 |title=Proceedings of the 10th ACM SIGPLAN International Workshop on Virtual Machines and Intermediate Languages |chapter-url=https://doi.org/10.1145/3281287.3281295 |chapter=Two decades of smalltalk VM development: live VM development through simulation tools |publisher=ACM Digital Library |pages=57–66 |doi=10.1145/3281287.3281295 |isbn=9781450360715 |s2cid=53116661 |url=https://hal.archives-ouvertes.fr/hal-01883380/file/hal.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://hal.archives-ouvertes.fr/hal-01883380/file/hal.pdf |archive-date=2022-10-09 |url-status=live |access-date=2020-11-09}}</ref> written in Squeak.
