The Lithuania Coat of Arms Flag is a variant of the national flag of Lithuania that incorporates heraldic and folkloric elements alongside the traditional horizontal tricolour of yellow, green, and red. In this design, the central feature is a green shield bearing the Vytis (the Lithuanian Coat of Arms), depicted in white as an armored knight on horseback holding a raised sword and shield. A vertical decorative band runs through the hoist side of the flag, featuring traditional Lithuanian folk ornamentation in white on green, visually linking the modern tricolour with historic Baltic textile motifs.

Historically, the Vytis has been a core symbol of Lithuanian statehood since the Grand Duchy of Lithuania in the Middle Ages, representing sovereignty, military defense, and continuity of the nation. While this specific flag variant is not an official state flag, it is commonly used in cultural, patriotic, and diaspora contexts to emphasize Lithuania’s medieval heritage and national identity. The combination of the modern tricolour with the historic coat of arms reflects a broader tradition in Lithuanian vexillology of blending contemporary national symbols with deep-rooted heraldic imagery, reinforcing Lithuania’s historical continuity from medieval statehood to the present day.
