Cullin is a male name with English origins. It is pronounced as KUH-lin (/kəˈlɪn/). This name is also spelled as Cullen. The name Cullin has been given to baby boys in the United States since at least 1917, and it has maintained a consistent but not overly popular ranking. In recent years, it has been given to around 5 to 23 newborns annually, placing it within the top 12,000 names for boys. Cullin may be associated with the Twilight series by Stephenie Meyer, as one of the main characters bears this name. It can also be seen as a modern twist on the traditional Irish surname, which means "holly tree" or "holly grove."
