Robert Lauder of The Bass (born before 1504 – died June 1576) was an important noble in Haddingtonshire, the Merse, and Fife. Stodart remarks that "to 1600 the barons of the Bass sat in almost every parliament". He was a firm supporter of Mary, Queen of Scots whom he accompanied to Carberry Hill on 14 June 1567, and fought for at the battle of Langside.
