Ninian Ross, 3rd Lord Ross of Halkhead (died February 1555/6), was a Scottish nobleman.
The Rosses of Halkhead, or Hawkhead, in Renfrewshire, were a Lowland family, not apparently related to the Earls of Ross or the Highland family of Ross of Balnagown.
[1] Following the death of his father at the Battle of Flodden, Ross had by 1514 obtained sasines of his father's lands in Melville, Renfrew and Tarbert.
He attended the parliaments of James V of Scotland frequently over the next 25 years.
On 30 June 1534 he ratified Scotland's peace treaty with England.
