Lyngby

The club was first founded on 8 April 1906 but it was disbanded again in 1915 due to problems with where they were allowed to play. On 30 March 1921, 30 young people from the football department of Lyngby IF decided to break away and start their own club. They named it Lyngby Boldklub af 1921. For the first few years, they played at Lundtofte Flyveplads, using the flight hangars as locker rooms. In 1949 the club moved to the area where the present-day Lyngby Stadion is located.

Lyngby was the first club in Denmark to wear the club's name on the kits, which happened in 1961. In 1983 the club became Danish champions for the first time and in 1984 the club played in the European Cup losing to Sparta Prague with 1–2,0–0 in the second round after beating KS Elbasani in the first round with 3–0,3–0. In 1986 the club was the first one to win its group in the UEFA Intertoto Cup without loss of points.

The club won its second Danish championship in 1992 on Gentofte Stadion. In 1996 the club was eliminated from the UEFA Cup by Club Brügge, even though playing a 1–1 draw in Belgium. 1996 was also the year when Lyngby's chairmen, Flemming Østergaard and Michael Kjær sold team captain Larsen to FC Copenhagen. The sale sparked harsh protests among the fans. In 1997 Østergaard and Kjær left Lyngby to become chairmen in FC Copenhagen. They were joined by striker Jónsson.

In December 2001 the club went bankrupt and was forced to finish the season using only amateur players. Hardly surprising, the team finished the season in last place and was subsequently relegated an additional two leagues due to the bankruptcy. As a result, the team went straight from playing in the Superliga to playing in the amateur league Danmarksserien, just below the three Danish pro leagues. In 2003 the team was promoted to the 2nd Division (the third best league), as winner of Danmarksserien, and on 18 June 2005 the team gained promotion to the 1st Division by finishing 3rd in the 2nd Division.

In the 2006–07 season the team won the Danish 1st Division thus returning to the top flight only five and a half seasons after going bankrupt. Another highlight of the 2006–07 season occurred on 12 April 2007 as Lyngby advanced to the semi-finals of the Danish Cup for the first time in several years, by winning 1–0 against AC Horsens on Lyngby Stadion.

Lyngby achieved a third place in the 2016-17 season, just a season after being promoted from the 1. Division. In the second half of the 2017-18 season, however, the club experienced financial difficulties, due to irregularities at the club owner, Hellerup Finans, which later went bankrupt. This led to the departure of several key players, before, on 9 February 2018, the club was bought and saved by a group of local business people and fans known collectively as Friends of Lyngby. This was not enough for Lyngby to hold its place in the Superliga, as the club lost two play-off matches against 1. Division number 3, Vendsyssel FF, being relegated to 1. Division. Just over a year later, on 2 June 2019, fortunes were reversed, as Lyngby, finishing 3rd in 1. Division, won 3–2 on aggregate against Vendsyssel FF, securing its re-promotion to the top flight.

On May 28, 2024, it was announced that Philadelphia based Union Sports and Entertainment had entered into a strategic partnership with Lyngby Boldklub, also acquiring a minority stake in the club.
