Colby has been used as a masculine given name since at least the 18th century. It first entered the U.S. Top 1000 Male Names in 1968 and peaked at #99 in 2001. Its peak was likely influenced by the appearance of Colby Donaldson on the highly watched second season of the reality television series Survivor, Survivor: The Australian Outback. In Canada, the name reached #81 that same year.
Other male associations include singer Colby O’Donis, who appeared on Lady Gaga’s 2008 hit “Just Dance”; FBI agent Colby Granger in the television series Numb3rs; ranch hand Colby Mayfield in Yellowstone; and social-media personality Colby Brock. The wealthy Colby family also appeared in the television series Dynasty and its 1985–1987 spin-off, The Colbys, although Colby was used as a surname.
As of 2025, Colby ranked as the 615th most popular male name in the United States and the 224th most popular male name in England and Wales.
The exact spelling Colby remains uncommon for females. One important fictional bearer was Colby Chandler, a female character born on the soap opera All My Children in 1999 who later became a regular character. Another notable bearer is American actress Colby Minifie (b. 1992), known for Jessica Jones, Fear the Walking Dead and The Boys. Despite these associations, Colby ranked only approximately #2,828 among American girls in 2025.
The feminine spelling Colbie was popularized by American singer-songwriter Colbie Caillat (b. 1985), who rose to prominence with her 2007 hit “Bubbly.” Although the spelling had been given to hundreds of girls annually for more than a decade, it did not cross the numerical threshold required to enter the U.S. Top 1000 Female Names until 2025, when it ranked at #881.
