Tinley is from the Old English Tynni's lēah — Tynni's clearing/meadow — historically a Yorkshire surname. The name is part of the broader 2010s-2020s American taste for short, sharp surname-as-given-name choices alongside Tinsley, Hadley, Brinley, and Kinsley. Tinley Beats — American TikTok creator. Tinley Hartung — American competitive cheerleader. Tinley Foster — American gymnast. The Yorkshire surname origin traces to the Yorkshire village of Tinsley near Sheffield; the modern American Tinley spelling has emerged as the more accessible, modern feminine form.
Tinley does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
