Kinslee is a modern American spelling of Kinsley, an English surname and place name usually explained as "king's meadow" or "king's clearing", from the Old English cyne, royal, and leah, clearing. The -lee ending ties it to Paislee, Hadlee and the other respelled surname names that American parents embraced in the 2010s. Kinslee peaked at number 652 in 2017, slipped out of the US top 1000 in 2024 and is back at number 956 among girls' names in 2025.
