The 10 cm Kanone 04 (10 cm K 04) was a field gun used by Germany in World War I. It was the second heavy gun with modern recoil system accepted by the German Army. It was produced as a replacement for the 10 cm K 99 and the lange 15 cm Kanone 92. Although the standard version lacked a gunshield, some models, such as the 10 cm K 04/12, were fitted with a special gunshield and some other minor modifications. There was only 32 in service at the outbreak of the war.^[2]

It could be transported in one load by a team of six horses, or it could be broken down into two loads (tandem hitches) for crossing rough terrain.
