'''Google Code Jam''' is an international programming competition hosted and administered by [[Google]]. The competition began in 2003 as a means to identify top engineering talent for potential employment at Google. The competition consists of a set of [[algorithm]]ic problems which must be solved in a fixed amount of time. Competitors may use any [[programming language]] and [[Development environment (software development process)|development environment]] to obtain their solutions. From 2003 to 2007, Google Code Jam was deployed on [[Topcoder]]'s platform and had quite different rules. Since 2008 Google has developed their own dedicated infrastructure for the contest.

Starting from 2015, Google also runs Distributed Code Jam, with the focus on [[distributed algorithm]]s. This is run in parallel with the regular Code Jam, with its own qualification and final round, for a top prize of $10,000, but is only open for people who qualify to Round 2 of Code Jam (up to 3000 people).

Several Google Code Jam problems have led to academic research.<ref>{{cite journal |last1=Dymchenko |first1=Sergii |last2=Mykhailova |first2=Mariia |title=Declaratively solving tricky google code jam problems with prolog-based ECLiPSe CLP system |journal=Roceedings of the 30th Annual ACM Symposium on Applied Computing |pages=2122–2124 |doi=10.1145/2695664.2696032 |url=https://dl.acm.org/citation.cfm?id=2696032 |accessdate=4 August 2018|year=2015 |isbn=9781450331968 }}</ref>
