Ninian Ross, 3rd Lord Ross

Ninian Ross, 3rd Lord Ross of Halkhead (died February 1555/6), was a Scottish nobleman.

Origins
Ross was the son and heir of John Ross, 2nd Lord Ross and Christian, the daughter of Sir Archibald Edmonstone. 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.

Career
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. He died in February 1555/6.
