'''Jack''' is a [[given name]] of English origin, originally a diminutive of [[John (given name)|John]]. Alternatively it may commonly be a diminutive of [[Jacob (name)|Jacob]], its French variant [[Jacques]], or given names like [[Jackson (name)|Jackson]] which have been derived from surnames.<ref name="think"/> Since the late 20th century, Jack has become one of the most common names for boys in many English-speaking countries. Jack is also used to a lesser extent as a female given name, often as a shortened version of [[Jacqueline (given name)|Jacqueline]].<ref name="JackFemaleUS" />

The word "jack" is also commonly used in other contexts in English for many occupations, objects and actions, linked to the use of the word as a metaphor for a common man.

==Origin==
Jack is thought by some to have hailed from the earlier Jackin (from the name Jankin).<ref name="think">{{cite web|url=http://www.thinkbabynames.com/meaning/1/Jack|title=Jack|publisher=Thinkbabynames.com|date=n.d.|access-date=March 30, 2012}}</ref><ref>{{cite web|url=http://www.behindthename.com/name/jack|title=Behind the Name: Meaning, Origin and History of the Name Jack|first=Mike|last=Campbell|publisher=Mike Campbell|work=Behind the Name|date=n.d.|access-date=March 30, 2012}}</ref> Alternatively, it may be derived from an [[Anglicisation of names | anglicisation]] of [[Jacques]], the French form of the name [[James (given name)|James]] or [[Jacob (name)|Jacob]].<ref name="think"/> There is also a theory that it is [[Celtic languages|Celtic]] in origin, meaning "healthy, strong, full of vital energy" (compare the [[Welsh language|Welsh]] word ''iach'', "health"), from a putative [[British language (Celtic)|Ancient British]] ''Yakkios''.<ref>{{Cite web |title=Jack - Baby Name Meaning, Origin and Popularity |url=https://www.thebump.com/b/jack-baby-name |access-date=2025-03-22 |website=www.thebump.com |language=en}}</ref> Both the name and the word "jack" were long used as a term to refer to any man, especially of the common classes.<ref name="Encyclopedia"/><ref name=dictionary>{{cite web|title=Dictionary entry, jack|publisher=[[Ask.com]]|work=[[Dictionary.com]]|url=http://dictionary.reference.com/browse/jack|access-date=March 30, 2012}}</ref>

==Frequency==
In several English-speaking countries, Jack has become increasingly used as a formal name, rather than being a mere nickname as it traditionally has been. In its own right, it is now more popular than John, James, and Jacob. In recent years{{when?|date=May 2024}}, Jack has been the most common given name for boys in the United Kingdom, Ireland, and Australia, and has grown in popularity in the United States and Canada.

John, from which Jack was originally derived, was, along with William, the most frequent male name throughout the 19th century and in the first half of the 20th century.<ref name="GalbiFreq2002">{{cite journal
