Bly is English in Origin.

Bly is an English surname-turned-given name deriving from Old English blīþe, meaning "cheerful, kind, gentle," source of the modern word blithe. Through Middle English, the byname signified a pleasant or good-natured person and later produced several spellings in Britain and Ireland. Pronounced like "blye" (rhymes with fly), the sleek one-syllable form feels modern while carrying an old, positive sense of temperament.

As a personal name, Bly is rare and largely unisex, used in English-speaking countries for its minimalist punch and literary lilt. The surname is familiar via journalist Nellie Bly and poet Robert Bly, and it sits alongside cognate spellings and variants such as Blythe, Blyth, and Bligh; related forms include Blithe as a vintage variant. Usage as a first name has increased modestly in the 21st century, often chosen as a pared-back alternative to Blythe with the same bright, buoyant meaning.
