Cash is an English surname that goes back to the Old French casse, a box or chest, and meant "box maker"; today most people simply hear the word for "money". As a first name it owes almost everything to country legend Johnny Cash, the Man in Black. Cash entered the US top 1000 in 2003, peaked at number 243 in 2013 and has stayed close to that level since, ranking 287th among boys' names in 2025.
