Meaning & origin

Billie is a name with a distinctive vintage charm, first recorded in the United States in 1886. After peaking in popularity in 1930, the name experienced a long decline before beginning a steady rise again in 2009. By the 2020s, it had climbed back into the top 1,000, ranking 691st in 2024, with approximately 1 in 3,930 girls receiving the name. The name's revival is particularly notable in states like Idaho, Mississippi, and Utah, where it has found renewed favor. Billie originated as a diminutive of William, a classic name of Germanic origin meaning 'resolute protection'. Its modern appeal may be attributed to its soft, friendly sound and its association with strong, creative figures, though its recent uptick also reflects a broader trend of reviving vintage nicknames.

Billie is a diminutive of William, which derives from the Old Norman French 'Williame' and ultimately from the Germanic elements 'wil' (will, desire) and 'helm' (helmet, protection). It emerged as a standalone given name in the 19th century, often used as a feminine form of Billy. The name gained popularity in the United States in the early 20th century, especially in the 1920s and 1930s, and has seen a revival in recent years.
