Dalen is a modern English name that first appeared in U.S. birth records in 1941, though it remained rare for decades. Its peak year was 2001, when it reached its highest rank. Since 2002, its usage has been gradually declining, reflecting a falling trajectory. In 2025, it ranked 5,861 with an incidence of 1 in 113,872 newborns. While top states are not recorded for Dalen, similar names like Dalton have seen wider regional variation. As a variant of Dalton or Dale, Dalen carries the pastoral image of a valley, giving it a quiet, grounded feel. Its simplicity and modern sound have made it a choice for parents seeking an uncommon but familiar-sounding alternative to more popular names like Caden or Brayden. The name has not been strongly associated with any particular region or cultural group, remaining a niche pick in the broader landscape of American baby names.

Dalen likely originated as a modern variant of names like Dalton, which is of English origin and means 'town in the valley' from Old English 'dæl' (valley) and 'tūn' (settlement). It may also be a respelling of Daelan or Daylen. The name has been in sporadic use in the United States since the mid-20th century, particularly in the 1990s and early 2000s.
