The flower name comes from the Old English word dægeseage, meaning "day's eye".

Linda Rosenkrantz and Pamela Redmond Satran wrote in their 2007 book Baby Name Bible that Daisy has a "fresh, wholesome, and energetic" image.

In Louisa May Alcott's Little Women, a character named Margaret is "Meg" to her family, but "Daisy" to her wealthy would-be-friends.

It was the 294th most common name for all females during the 1990 United States census.

Daisy has ranked among the top 100 names for girls in the United Kingdom since 1996 and in the past decade in Australia, Ireland, and New Zealand.
