The Flag of Pest County is a historical symbol representing one of the 19 counties of Hungary. It was officially used between 1876 and 1950 when administrative divisions were reorganized. The flag features three horizontal stripes in the colors of red, white, and green, with the white stripe being twice the size of both the red and green ones. This particular design is a simplified version of the coat of arms of Pest County, which displays an image of St. George on a horse slaying a dragon. The flag serves as a reminder of the historical identity and heritage of Pest County, even though it no longer exists in its original form as part of Hungary's administrative structure.
