'''Boo''' is an [[Object oriented programming|object-oriented]], [[Type system#Static typing|statically typed]], [[general-purpose programming language]] that seeks to make use of the [[Common Language Infrastructure]]'s support for [[Unicode]], [[I18n|internationalization]], and web applications, while using a [[Python (programming language)|Python]]-inspired syntax<ref>{{cite web |url=http://boo.codehaus.org/BooManifesto.pdf |title=The boo Programming Language |author=Rodrigo Barreto de Oliveira |year=2005 |access-date=February 22, 2009 |url-status=dead |archive-url=https://web.archive.org/web/20090206045607/http://boo.codehaus.org/BooManifesto.pdf |archive-date=February 6, 2009}}</ref> and a special focus on language and compiler extensibility. Some features of note include [[type inference]], [[generator (computer science)|generators]], [[multimethods]], optional [[duck typing]], [[Macro (computer science)|macros]], true [[Closure (computer science)|closures]], [[currying]], and [[first-class function]]s.

Boo was one of the three scripting languages for the [[Unity (game engine)|Unity game engine]] ([[Unity Technologies]] employed De Oliveira, its designer), until official support was dropped in 2014 due to the small userbase.<ref>{{cite web |url=https://blogs.unity3d.com/2014/09/03/documentation-unity-scripting-languages-and-you/ |title=Documentation, Unity scripting languages and you |author=aleksandr |date=September 3, 2014 |website=Unity Blogs}}</ref> The Boo Compiler was removed from the engine in 2017.<ref>{{cite web |url=https://blogs.unity3d.com/2017/08/11/unityscripts-long-ride-off-into-the-sunset/ |title=UnityScript's long ride off into the sunset |author=Richard Fine |date=August 11, 2017 |website=Unity Blogs}}</ref> Boo has since been abandoned by De Oliveira, with development being taken over by Mason Wheeler.<ref>{{cite web |url=https://github.com/boo-lang/boo/issues/201 |title=State of Boo · Issue #201 · boo-lang/boo |date=October 2, 2019 |website=GitHub |access-date=January 19, 2023}}</ref>
