Warren is an English given name of Norman origin, derived from the Old French name Warenne, which was composed of the elements wari meaning "spear" and ann meaning "noble". This name has been historically popular in England and other English-speaking countries. It was often used as a surname before becoming common as a given name again in the 20th century.
The name Warren has seen fluctuations in popularity over time, with a notable spike in usage during the early 1920s, particularly in 1921 when it was given to nine newborns. However, this trend did not continue consistently as shown by the decrease in births attributed to the name in the following year, 1923, with only five newborns being named Warren. In total, over these two years, the name Warren appeared on fourteen birth certificates.
