About Weston County Fair
The Weston County Fair is a tradition dating back to 1904. The event was held sporadically until 1909, again in 1915-1916 and from 1925 to 1928. Since 1937, following donation of the land that today comprises the Weston County Fairgrounds, the fair much as we know it today has been held. The annual week-long celebration begins with a parade through downtown Newcastle and culminates with the second round of the Weston County Junior Rodeo the following Sunday.
The 2021 Weston County Fair is July 23-30 in Newcastle, WY.
