The House of Gediminas (Lithuanian: Gediminaičių dinastija), or simply the Gediminids,[a] were a dynasty of monarchs in the Grand Duchy of Lithuania that reigned from the 14th to the 16th century.

[1] The Gediminas' Cap was used during the inaugurations of Gediminids as Lithuanian monarchs in the Vilnius Cathedral and symbolized the dynasty's continuity.

Others (e. g. the Golitsyn (Galitzine), Kurakin and Trubetskoy) moved to Muscovy, became thoroughly Russified and are among the princely families of Russia.

In Poland, some Gediminid families (such as Olelkowicz-Słucki, Wiśniowiecki, Zbaraski) are extinct, but others survive to the present: Chowański, Czartoryski, Sanguszko, Siesicki (Dowmont-Siesicki, Szeszycki), and Koriatowicz-Kurcewicz.

The Russian Gediminid families include Bulgakov, Golitsin, Kurakin, Khovansky, Troubetzkoy, Mstislavsky, Belsky, and Volynsky.
