The family of Gediminas is a group of family members of Gediminas, Grand Duke of Lithuania (ca. 1275–1341), who interacted in the 14th century. The family included the siblings, children, and grandchildren of the Grand Duke and played the pivotal role in the history of Lithuania for the period as the Lithuanian nobility had not yet acquired its influence. Gediminas was also the forefather of the Gediminid dynasty, which ruled the Grand Duchy of Lithuania from 1310s or 1280s to 1572.

Gediminas' origins are unclear, but recent research suggests that Skalmantas, an otherwise unknown historical figure, was Gediminas' grandfather or father and could be considered the dynasty's founder. Because none of his brothers or sisters had known heirs, Gediminas, who sired at least twelve children, had the advantage in establishing sovereignty over his siblings. Known for his diplomatic skills, Gediminas arranged his children's marriages to suit the goals of his foreign policy: his sons consolidated Lithuanian power within the Grand Duchy of Lithuania, while his daughters established or strengthened alliances with the rulers of areas in modern-day Russia, Ukraine and Poland.

The relationships among Gediminas' children were generally harmonious, with the notable exception of Jaunutis, who was deposed in 1345 by his brothers Algirdas and Kęstutis. These two brothers went on to provide a celebrated example of peaceful power-sharing. However, Gediminas' many grandchildren and their descendants engaged in power struggles that continued well into the 15th century. Gediminas' grandchildren converted Lithuania to Christianity and inaugurated the first personal union with Poland.

Because written sources of the era are scarce, Gediminas' ancestry, early life, and assumption of the title of Grand Duke in ca. 1316 are obscure and continue to be the subject of scholarly debate. Various theories have claimed that Gediminas was either his predecessor Grand Duke Vytenis' son, his brother, his cousin, or his hostler. For several centuries only two versions of his origins circulated. Chronicles—written long after Gediminas' death by the Teutonic Knights, a long-standing enemy of Lithuania—claimed that Gediminas was a hostler to Vytenis; according to these chronicles, Gediminas killed his master and assumed the throne. Another version introduced in the Lithuanian Chronicles, which also appeared long after Gediminas' death, proclaimed that Gediminas was Vytenis' son. However, the two men were almost the same age, making this relationship unlikely. In 1868, a letter issued by the Council of Riga in 1323 was published that contained a small note mentioning Vytenis as "the brother and predecessor" of Gediminas. After the letter came to light, textbooks almost universally represented Vytenis and Gediminas as brothers. However, historian Tomas Baranauskas believes the word "brother" has been interpreted too literally, and that the two were in fact cousins.
