About Prince George's County Fair

The Prince George's County Fair in Upper Marlboro celebrates Maryland's second-most populous county and one of the most affluent majority-Black counties in the United States — the county surrounds Washington DC on two sides and combines active farming communities in the rural Patuxent River watershed with suburban communities tied to the federal government. The fair traces back to 1842, making it one of Maryland's longest-running agricultural traditions.

What to Expect

Expect livestock shows, 4-H and FFA competitions, carnival rides, live entertainment, diverse local food vendors, and a large fair drawing from Prince George's County's diverse and economically dynamic community.
