The '''Portland Pattern Repository''' ('''PPR''') is a repository for [[design pattern (computer science)|computer programming design pattern]]s. It was accompanied by a companion website, [[WikiWikiWeb]], which was the world's first [[wiki]].

The repository has an emphasis on [[Extreme Programming]]. It is hosted by Cunningham & Cunningham (C2) of [[Portland, Oregon]], at http://c2.com/ppr/. The PPR's [[motto]] is "[http://c2.com/cgi/wiki?PeopleProjectsAndPatterns People, Projects & Patterns]."

On [[17 September]] [[1987]], programmer [[Ward Cunningham|Howard G. (Ward) Cunningham]], then with [[Tektronix]], co-published withand [[Apple Computer]]'s [[Kent Beck]] co-published the paper ''[http://c2.com/doc/oopsla87.html Using Pattern Languages for Object-Oriented Programs]''. This paper about programming patterns, was inspired by [[Christopher Alexander]]'s architectural concept of "patterns",. It was written for the [[1987]] [[OOPSLA]] programming conference organized by the [[Association for Computing Machinery]]. Cunningham's and Beck's idea became popular among programmers, because it helped them exchange programming ideas in a format that is easy to understand.

Cunningham & Cunningham, the programming consultancy which would eventually host the PPR on its Internet ___domain, was incorporated in [[Salem, Oregon]], on [[1 November]] [[1991]] and is named after Ward and his wife [[Karen R. Cunningham]], a mathematician, school teacher, and school director. Cunningham & Cunningham registered their Internet ___domain c2.com on [[October 23 October]] [[1994]].

Ward created the ''Portland Pattern Repository'' on c2.com as a means to help [[object-oriented programming|object-oriented programmers]] publish their computer programming patterns by submitting them to him. Some of those programmers attended the OOPSLA and [http://st-www.cs.uiuc.edu/~plop/ PLoP] conferences about object-oriented programming, posting their ideas on the PPR and exchanging e-mail messages with Ward.

The PPR is accompanied on c2.com by the first ever [[wiki]] (a collection of reader-modifiable Web pages), which is called '''''[[WikiWikiWeb]]'''''. It is located at http://c2.com/cgi/wiki.
