National flag
A banner with a white on red cross is attested as having been used by the kings of Denmark since the 14th century. An origin legend with considerable impact on Danish national historiography connects the introduction of the flag to the Battle of Lindanise of 1219. The elongated Nordic cross, which represents Christianity, reflects its use as a maritime flag in the 18th century. The flag became popular as a national flag in the early 16th century. Its private use was outlawed in 1834 but again permitted by a regulation of 1854. The flag holds the world record of being the oldest continuously used national flag, that is since 1625.

In 1748, a regulation defined the correct lengths of the two last fields in the flag as 6/4. In May 1893 a new regulation to all chiefs of police stated that the police should not intervene, if the two last fields in the flag were longer than 6/4 as long as these did not exceed 7/4, and provided that this was the only rule violated. This regulation is still in effect today and thus the legal proportions of the National flag today are 3:1:3 in width and anywhere between 3:1:4.5 and 3:1:5.25 in length. No official definition of "Dannebrog rød" exists. The private company Dansk Standard, regulation number 359 (2005), defines the red colour of the flag as Pantone 186c.

The white on red cross emblem originates in the age of the Crusades. In the 12th century, it was also used as war flag by the Holy Roman Empire. In the Gelre Armorial, dated 1340–1370, such a banner is shown alongside the coat of arms of the king of Denmark. This is the earliest known undisputed colour rendering of the Dannebrog. At about the same time, Valdemar IV of Denmark displays a cross in his coat of arms on his Danælog seal (Rettertingsseglet, dated 1356). The image from the Armorial Gelre is nearly identical to an image found in a 15th century coat of arms book now located in the National Archives of Sweden (Riksarkivet). The seal of Eric of Pomerania (1398) as king of the Kalmar union displays the arms of Denmark's chief dexter, three lions. In this version, the lions are holding a Dannebrog banner. The reason why the kings of Denmark in the 14th century began displaying the cross banner in their coats of arms is unknown. Caspar Paludan Müller (1873) suggested that it may reflect a banner sent by the pope to support the Danish king during the Livonian Crusade. Adolf Ditlev Jørgensen (1875) identifies the banner as that of the Knights Hospitaller, which order had a presence in Denmark from the later 12th century. Several coins, seals, and images exist, both foreign and domestic, from the 13th to 15th centuries and even earlier, showing heraldic designs similar to Dannebrog, alongside the royal coat of arms (three blue lions on a golden shield.) There is a record suggesting that the Danish army had a "chief banner" (hoffuitbanner) in the early 16th century. Such a banner is mentioned in 1570 by Niels Hemmingsøn in the context of a 1520 battle between Danes and Swedes near Uppsala as nearly captured by the Swedes but saved by the heroic actions of the banner carrier Mogens Gyldenstierne and Peder Skram. The legend attributing the miraculous origin of the flag to the campaigns of Valdemar II of Denmark (r. 1202–1241) was recorded by Christiern Pedersen and Petrus Olai in the 1520s. Hans Svaning's History of King Hans from 1558 to 1559 and Johan Rantzau's History about the Last Dithmarschen War, from 1569, record the further fate of the Danish hoffuitbanner: According to this tradition, the original flag from the Battle of Lindanise was used in the small campaign of 1500 when King Hans tried to conquer Dithmarschen (in western Holstein in the north Germany). The flag was lost in a devastating defeat at the Battle of Hemmingstedt on 17 February 1500. In 1559, King Frederik II recaptured it during his own Dithmarschen campaign. In 1576, the son of Johan Rantzau, Henrik Rantzau, also writes about the war and the fate of the flag, noting that the flag was in a poor condition when returned. He records that the flag after its return to Denmark was placed in the cathedral in Slesvig. Slesvig historian Ulrik Petersen (1656–1735) confirms the presence of such a banner in the cathedral in the early 17th century and records that it had crumbled away by about 1660. Contemporary records describing the battle of Hemmingstedt make no reference to the loss of the original Dannebrog, although the capitulation state that all Danish banners lost in 1500 was to be returned. In a letter dated 22 February 1500 to Oluf Stigsøn, King John describes the battle but does not mention the loss of an important flag. In fact, the entire letter gives the impression that the lost battle was of limited importance. In 1598, Neocorus wrote that the banner captured in 1500 was brought to the church in Wöhrden and hung there for the next 59 years until it was returned to the Danes as part of the peace settlement in 1559.

Used as a maritime flag since the 16th century, the Dannebrog was introduced as a regimental flag in the Danish army in 1785, and for the militia (landeværn) in 1801. From 1842, it was used as the flag of the entire army. During the first half of the 19th century, in parallel to the development of Romantic nationalism in other European countries, the military flag increasingly came to be seen as representing the nation itself. Poems of this period invoking the Dannebrog were written by B. S. Ingemann, N. F. S. Grundtvig, Oehlenschläger, Chr. Winther and H. C. Andersen. Special permission to use the Splitflag was given to individual institutions and private companies, especially after 1870. In 1886, the war ministry introduced a regulation indicating that the flag should be flown from military buildings on thirteen specified days, including royal birthdays, the date of the signing of the Constitution of 5 June 1849 and on days of remembrance for military battles. In 1913, the naval ministry issued its own list of flag days. On 10 April 1915, the hoisting of any other flag on Danish soil was prohibited. This prohibition has been lifted on 24 June 2023, after a Supreme Court ruling. From 1939 until 2012, the yearbook Hvem Hvad Hvor included a list of flag days. As of 2019 flag days can be viewed at the "Ministry of Justice (Justitsministeriet)" as well as "The Denmark Society (Danmarks Samfundet)".

They have their own official flags. Some areas in Denmark have unofficial flags. While they have no legal recognition or regulation, they can be used freely. The regional flags of Bornholm and Ærø are occasionally used by locals of those islands and in tourist related businesses. The proposal for a flag of Jutland has hardly found any actual use, maybe in part due to its peculiar design. The flag of Vendsyssel (Vendelbrog) is seen infrequently, but many locals recognise it. According to an article in the newspaper Nordjyske, the flag had been used in the former insignia of Flight Eskadrille 723 of Aalborg Air Base, in the 1980s.
