'''VisualWorks''' (formerly '''ObjectWorks''', afterward '''Cincom Smalltalk''') is a cross-platform implementation of the [[Smalltalk]] language. It is implemented as a development system based on ''images'', which are dynamic collections of software objects, each contained in a [[system image]].

The lineage of VisualWorks goes back to the first Smalltalk-80 implementation by [[PARC (company)|Xerox PARC]]. In the late 1980s, a group of Smalltalk-80 developers spun off ParcPlace Systems to further develop Smalltalk-80 as a commercial product. The commercial product was initially named ObjectWorks, and then VisualWorks. On August 31, 1999, the VisualWorks product was sold to [[Cincom Systems]]. VisualWorks runs under many operating systems, including  [[Microsoft Windows|Windows]], [[macOS]], [[Linux]], and several [[Unix]] versions.

VisualWorks supports cross-platform development projects, because of its built-in multi-platform features. For example, a [[graphical user interface]] (GUI) application needs to be developed only once, and can then be switched to different widget styles. A VisualWorks application can be run on all supported platforms with no modifications. Only the [[virtual machine]] is platform-dependent.
