Udny Green (Scottish Gaelic: Olldanaidh; Doric: Widnie Green) is a village in Aberdeenshire, Scotland, located immediately south-west of Pitmedden. It forms part of the parish of Udny, along with the nearby settlement of Udny Station.
Considered the last family jester of Scotland, Jamie Fleeman or Fleming (1713–1778) about 1734 was employed by the Laird of Udny. There were a number of annedotes printed about Fleeman, and in 1859, John B. Pratt published a set of stories that may have been related to Fleeman: The life and death of Jamie Fleeman, the Laird of Udny's fool.
On 22 September 1943, the Royal Engineers were called out to Udny Castle to investigate reports of an unexploded bomb. It was subsequently identified as a "flash bomb" used by the Luftwaffe at night to illuminate areas for navigation or photographic purposes.[citation needed]
The now-deconsecrated Udny Parish Church stands beside the village green, with the old kirkyard and Udny Mort House on the opposite side.
