Sigourney is an uncommon and unique given name of American origin, derived from the surname Sigourney which was brought to America by early settlers from England. It is often associated with the actress Sigourney Weaver, who is named after the poet Philip Sidney's sister, Mary Sidney Herbert, Countess of Pembroke, whose name was spelled "Sidney" in some sources. The name Sigourney has a distinct and elegant sound, ending with a soft "y" that gives it a unique rhythm. It is not typically associated with any specific meanings or origins outside of its connection to the actress.
The name Sigourney experienced a significant peak in popularity around the late 1980s and early 1990s with a high of 43 births in 1989, likely influenced by actress Sigourney Weaver's fame during this period. However, it has since become much less common, with recent years showing consistently low numbers of births, such as the most recent data point of 10 births in 2023.
