Lord Saltoun, of Abernethy, is a title in the Peerage of Scotland. It was created in 1445 for Sir Lawrence Abernethy. The title remained in the Abernethy family until the death in 1669 of his descendant the tenth Lady Saltoun. She was succeeded by her cousin Alexander Fraser, the eleventh Lord. He was the son of Alexander Fraser and Margaret Abernethy, daughter of the seventh Lord Saltoun. The title has remained in the Frasers of Philorth family ever since.

The seventeenth Lord was a Lieutenant-General in the Army and sat in the House of Lords as a Scottish Representative Peer from 1807 to 1853. His nephew, the eighteenth Lord, was a Scottish Representative Peer from 1859 to 1866. His son, the nineteenth Lord, and grandson, the twentieth Lord, were also Scottish Representative Peers, between 1890 and 1933 and 1935 and 1963, respectively. Since 1979, the title has been held by the latter's daughter, the 21st Lady Saltoun. She is head of the Frasers of Philorth and was also one of the ninety elected hereditary peers that remain in the House of Lords after the passing of the House of Lords Act 1999 (resigning her seat in the House in 2014).

The family seat is Inverey House, near Braemar, Aberdeenshire.
