The Julekalender (The Christmas Calendar) is a julekalender that originally aired in Christmas 1991. (a Norwegian version was made in 1994, and a Finnish version appeared in 1997). It was written and performed almost entirely by a trio of Danish comedy musicians called De Nattergale with financial and technical assistance from TV2, a Danish television company. It was hugely successful at the time, causing many invented phrases from the series to enter popular culture and was later released on VHS and subsequently DVD.

It consisted of 24 episodes (one for each day of December until Christmas Eve), as has been typical for most other TV "Christmas calendars" before and since The Julekalender.
