The name Finley is a boy's name of Scottish, Irish origin meaning "fair-haired hero". Finley is ranked #287 on our popularity charts and is often added to lists like New Baby Names on the Rise and discussed in our forums with posts like "Name sightings".
From the experts:
Scottish royal name (it belonged to Macbeth's father) riding the wave of Finn names. Chris O'Donnell used it for one of his sons, and Angie Harmon and Jason Sehorn did a gender switch when they named their daughter Finley.
Though Finley has not been used for both sexes for enough years to make it onto our unisex names graph, the name at most recent count was running at almost two to one in favor of the girls, no doubt heavily influenced by Harmon and Sehorn's use of it for their little girl.
