'''Universal Network Objects''' ('''UNO''') is the [[software component|component model]] used in the [[OpenOffice.org]] and [[LibreOffice]] computer software [[application suite]]s. It is interface-based and designed to offer interoperability between different [[programming language]]s, object models and machine architectures, on a single machine, within a LAN or over the Internet.

Users can implement or access UNO components from any programming language for which a [[language binding]] exists. Complete UNO language bindings exist for [[C++]] (compiler-dependent), [[Java (programming language)|Java]], [[Object REXX]], [[Python (programming language)|Python]], and [[Tcl (programming language)|Tcl]]. Bindings allowing access, but not writing, to components exist for [[StarOffice Basic]], [[OLE Automation]] and the [[Microsoft .NET|.NET]] [[Common Language Infrastructure]]. In particular, this API is used by macros.

Universal Network Objects operate within the UNO Runtime Environment (URE).<ref>{{ cite web | url = http://svn.apache.org/repos/asf/openoffice/ooo-site/trunk/content/l10n/archive/Universal_i18n_framework.pdf | title = Universal I18n Framework for Office Applications: Technical Overview | first = Dieter | last = Loeschky |author2=Shanmugam Senthil  | year = 2001 | publisher = Sun Microsystems | location = Palo Alto | pages = 1–26 [8] | format = PDF | access-date = 18 May 2010 }}</ref>
