Gage is an English and French surname from the Old French gage, meaning "pledge" or "measure", originally a nickname for a moneylender or a pledge taker. As a first name it took off in the United States in the 1990s, partly through the little boy Gage Creed in Stephen King's Pet Sematary, and became a staple of the one-syllable surname style. Gage peaked at number 136 in 2003 and has slid steadily since, ranking number 973 among boys' names in 2025.
