Lainey is a modern English feminine name, usually explained as a pet form of Elaine, the French version of Helen. Helen derives from Greek Helena, commonly glossed as "torch" or "light," so Lainey is generally given the meaning "bright" or "shining one." A minority of dictionaries connect it instead to the English surname Lane, "path" or "lane," and treat the light meaning as secondary; the name's origin is not fully settled. It is pronounced LAY-nee in both American and British English.
Its best-known bearer is Lainey Wilson, the American country singer and songwriter who moved to Nashville as a young woman and reached the top of the country chart in 2020 with "Things a Man Oughta Know."
For most of its history in the United States, Lainey was uncommon: 13 girls received the name in 1980, when it sat at rank 5,245. It grew steadily through the 1990s and 2000s, reaching 163 births and rank 1,217 in 2000, then climbed far faster in the last few years. It stood at rank 250 in 2021, jumped to 54 in 2023, and in 2025 reached rank 30 with 5,738 births, its highest position and largest count to date.
