Meaning & origin

Jo is a short and spunky name that has maintained a steady presence in American naming culture. First recorded in 1881, it reached its peak popularity in 1954, when it ranked among the top names of the decade. In recent years, Jo has seen a resurgence, rising in usage since 2010, likely due to a renewed appreciation for simple, vintage nicknames as standalone names. Its highest concentration is found in California, reflecting its appeal in diverse, trend-forward regions. With a current 1-in-44,646 birth rate, Jo remains a rare but recognizable choice, offering a retro charm without feeling dated.

Jo originated as a diminutive of Josephine (feminine form of Joseph) or Joanna (feminine form of John), both of which trace back to Hebrew roots. Joseph comes from Yosef, meaning 'He will add', while John derives from Yochanan, meaning 'God is gracious'. In the United States, Jo gained popularity as an independent given name in the early 20th century, often used as a short form or middle name.
