Evan is a Welshmasculinegiven name derived from "lefen", a Welsh form for the name John. In other languages it could be compared to "Ivan", "Ian", and "Juan"; the name John itself is derived from the ancient Hebrew name יְהֹוחָנָןYəhôḥānān, which means "YHWH is gracious". Evan comes from Gaelic Eóghan meaning "youth" or "young warrior" and Scots for "right-handed". In Hebrew, the actual non-Proper noun, "evan/even/eban/eben", literally means "rock". It can also be the shortened version of the Greek name "Evangelos" (meaning messenger) or "Evander" (meaning good man). The name is also occasionally given to girls, as with actressEvan Rachel Wood. It may be encountered as a surname, but Evans is usual.
The popularity of the name Evan in the United States rose steadily over the last several decades, going from the 440th-ranked name in 1957 to peaking at the 35th-ranked name in 2009. It has since declined somewhat, and dropped out of the top 50 names in the US in 2013.
