Sydney

Meaning & origin

Sydney entered U.S. records for female births as early as 1886, but it was not until the late 20th century that it saw widespread use. The name reached its peak rank of 28 in the year 2000, when it was given to thousands of baby girls. Since then, it has been steadily declining in popularity; as of 2025 it sits at rank 348, with roughly 1 in every 1,841 newborn girls receiving the name. Sydney is most popular in the District of Columbia, Delaware, and Rhode Island, suggesting a preference in coastal and urban areas. The name shares roots with the masculine Sidney, but the spelling Sydney has become the dominant feminine form in the U.S., reflecting a modern trend of adapting surnames and place names into first names.

Sydney originated as a variant of Sidney, an English surname derived from the Old English elements 'sid' (wide) and 'eg' (island or meadow), meaning 'wide island' or 'broad meadow'. The name gained popularity as a given name due to the city of Sydney, Australia, itself named after British politician Lord Sydney. In the United States, Sydney emerged as a feminine form of Sidney in the late 19th century and became increasingly common for girls in the 20th century.
