What does the baby name “Sidney” mean?

Sidney is a charming name with Old English roots meaning wide island, a surname-turned-given-name with centuries of history that has worn well on both boys and girls.

Origin of the baby name Sidney

Sidney derives from the Old English place name Sidaneg, a location in Surrey, England, built from two elements: sid, meaning wide or broad, and eg, meaning island or low-lying land near water. The literal meaning is therefore wide island or wide water meadow, a name rooted in the English landscape. The place gave rise to the Sidney surname, which was borne by the influential Sidney family in Tudor England before gradually spreading into use as a given name.
