George Keith, 5th Earl Marischal (c. 1692–1778), was a Scottish nobleman known for his role in the Jacobite risings. He was a prominent supporter of the Jacobite cause, which aimed to restore the Stuart monarchy to the British throne. His loyalty to the Jacobite movement led him to fight in the Battle of Culloden in 1746. After the defeat of the Jacobites, Keith went into exile in France, where he continued to support the cause. He held various military positions and was involved in the French army. Keith's legacy is marked by his commitment to the Jacobite ideals and his noble lineage.
