Janet Stewart, Lady Ruthven

Janet Stewart, Lady Ruthven (c. 1500 – after 1564) was a Scottish noblewoman.

She was a daughter of John Stewart, 2nd Earl of Atholl and Lady Janet Campbell, a daughter of Archibald Campbell, 2nd Earl of Argyll and Elizabeth Stewart.

Janet Stewart married (1) Alexander Gordon, Master of Sutherland (died 1529), (2) Hugh Kennedy of Girvanmains (divorced), (3) in 1544, Henry Stewart, 1st Lord Methven (died 1552), and (4) in 1557, Patrick Ruthven, 3rd Lord Ruthven.

A Latin document drawn up at Dunrobin Castle on 4 November 1544 calls her "Dame Jean or Jonete Stewart, Mistress of the earldom of Sutherland and Lady of lordship of Methven". On that day, John Murray, the bailie of her estates, produced a royal letter ordering the tenants of Sutherland to pay rent to her for her jointure lands. The officer of the court at Dunrobin, Donald Skallag, read out the letters, and then Murquhard Murray explained in Scottish Gaelic the legal penalties if the rents were not paid.

In June 1545 Mary, Queen of Scots and Regent Arran granted Lord Methven and "Lady Jonet Stewart" some of the lands of Gorthy in Perthshire. Around the year 1550, Archibald Douglas, 6th Earl of Angus granted "Dame Jonet Stewart Lady Methven" and her son Henry Stewart, Lord Methven, rights over the marriage of a Forfarshire heiress Katherine Gorthy.
