Krystyn is a feminine given name of Welsh origin, derived from the word "crys" meaning "gold". It was traditionally used as a pet form of Kristin or Kristen, which are variations of the Greek name Christine, itself meaning "follower of Christ". The name Krystyn gained popularity in Wales during the 19th century and has since been adopted by other English-speaking countries. Today, it is often used as a unique and distinct given name for girls, rather than just a pet form.
The name Krystyn experienced significant popularity spikes between 1980 and 1990, with a peak of 51 births in 1990. However, its usage has declined consistently since the mid-90s, with only 6 births recorded each in 2010 and 2013. Overall, there have been 711 Krystyn births from 1967 to 2013.
