Lord Napier, of Merchistoun, is a title in the Peerage of Scotland. It was created in 1627 for Sir Archibald Napier, 1st Baronet. Earlier that year, he already held the Napier Baronetcy, of Merchistoun in the County of Midlothian, created in the Baronetage of Nova Scotia. The titles remained united until 1683, when the Baronetcy became dormant. It was revived in the early 19th century and is now held by another branch of the Napier family. Between 1683 and 1686, the Lords of Napier also held the Nicolson Baronetcy, of Carnock in the County of Stirling, and since 1725 the Scott Baronetcy, of Thirlestane in the County of Selkirk, both baronetcies created in the Baronetage of Nova Scotia. The latter one is held till today. Additionally, the tenth Lord was created Baron Ettrick in the Peerage
