Blood brother can refer to one of two things: a male related by birth, or two or more men not related by birth who have sworn loyalty to each other. This is in modern times usually done in a ceremony, known as a blood oath, where each person makes a small cut, usually on a finger, hand or the forearm, and then the two cuts are pressed together and bound, the idea being that each person's blood now flows in the other participant's veins. The act may carry a risk due to blood-borne diseases. The process usually provides a participant with a heightened symbolic sense of attachment with the other participant.

The Norsemen entering into the pact of foster brotherhood (Icelandic: Fóstbræðralag) involved a rite whereby they let their blood flow while they ducked underneath an arch formed by a strip of turf propped up by a spear or spears. An example is described in Gísla saga. In Fóstbræðra saga, the bond of Thorgeir Havarsson (Þorgeir Hávarsson) and Thormod Bersason (Þormóð Bersason) is sealed by such ritual as well, the ritual being called a leikr.

Örvar-Oddr's saga contains another notable account of blood brotherhood. Örvar-Oddr, after fighting the renowned Swedish warrior Hjalmar to a draw, entered into foster-brotherhood with him by this turf-raising ritual. Afterwards, the strand of turf was put back during oaths and incantations.
In the mythology of northern Europe, Gunther and Högni became the blood brothers of Sigurd when he married their sister Gudrun; in Wagner's Ring Cycle, the same occurs between Gunther and Wagner's version of Sigurd, Siegfried, which is marked by the "Blood Brotherhood Leitmotiv". Additionally, it is briefly stated in Lokasenna that Odin and Loki are blood brothers.

Blood brothers among larger groups were common in ancient Southeastern Europe where, for example, whole companies of soldiers would become one family through the ceremony. It was perhaps most prevalent in the Balkans during the Ottoman era, as it helped the oppressed people to fight the enemy more effectively; blood brotherhoods were common in what is today Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Montenegro, Serbia, Republic of North Macedonia. Christianity also recognized sworn brotherhood in a ceremony (known as Greek: adelphopoiesis, Slavic languages: pobratimstvo in the Eastern Orthodox churches; known as Latin: ordo ad fratres faciendum in the Roman Catholic church). The tradition of intertwining arms and drinking wine is also believed to be a representation of becoming blood brothers.

Among the Scythians, the covenantors would allow their blood to drip into a cup; the blood was subsequently mixed with wine and drunk by both participants. Every man was limited to having at most three blood brotherhoods at any time, lest his loyalties be distrusted; as a consequence, blood brotherhood was highly sought after and often preceded by a lengthy period of affiliation and friendship (Lucian, Toxaris). 4th-century BC depictions of two Scythian warriors drinking from a single drinking horn (most notably in a gold appliqué from Kul-Oba) have been associated with the Scythian oath of blood brotherhood.

The Hungarian hajduks had a similar ceremony, though the wine was often replaced with milk so that the blood would be more visible
