Meaning & origin

Sydna is a rare feminine variant of Sidney that first appeared in U.S. birth records in 1915 (the first recorded year for the name). The name reached its peak popularity in 1940, though it never achieved widespread usage, reflecting a pattern of steady but infrequent use over the decades. Despite its relatively low frequency, Sydna has maintained a stable trajectory with no significant resurgence in recent years. It remains an uncommon choice for parents seeking a vintage-sounding name with English origins.

Sydna is a feminine variant of Sidney, which originated as an English surname. The name Sidney is derived from the Old English elements 'sid' (wide) and 'ieg' (island), or from the French place name Saint-Denis. Sydna emerged as a given name in the early 20th century, primarily in the United States, as a less common alternative to Sydney.
