Sir Oliver Sinclair of Pitcairnis and Whitekirk (died circa 1576) was a favourite courtier of James V of Scotland. He was a Sheriff of Orkney.[1] A contemporary story tells that James V gave him the battle standard and command at the Battle of Solway Moss. Another story tells how at the end of his life he shamed the haughty servant of Regent Morton by showing him how his own prosperity had faded.
