A day beacon (sometimes daybeacon) is an unlighted nautical sea mark. A signboard identifying it is called a day mark. Day beacons typically mark channels whose key points are marked by lighted buoys. They may also mark smaller navigable routes in their entirety. They are the most common navigation aid in shallow water, as they are relatively inexpensive to install and maintain. Navigation around them is similar to that around other navigation aids.

The Kugelbake (German pronunciation: [ˈkuːɡl̩ˌbaːkə], lit. 'Ball Beacon') is a historic day beacon in the city of Cuxhaven, Germany, at the northernmost point of Lower Saxony, where the River Elbe flows into the North Sea. In the Low German dialect of the Middle Ages, the term bake referred to all navigational aids – including lighthouses. About 30 meters (100 feet) high and built of wood, the Kugelbake is the principal landmark of Cuxhaven; since 1913, it has been depicted on the city's coat of arms. Large wooden structures guiding mariners have stood on this spot for over 300 years.
