The House of Gualterio (in the past, also Gualtieri) is an Italian aristocratic family, with its first documented roots in the 12th century and links to France and the Stuarts. The Gualterio family has spawned various aristocratic titles including the extant Marquis of Corgnolo (1723) and, under the Jacobite peerage, Earl of Dundee (1705). The present head and heir to the titles is Luigi Gualterio (b. 1955).

History 
The Gualterio family bore the surname Gualterini or Gualcherini when Otto I, Holy Roman Emperor, around 975, appointed it among the hundred consul families for the government of Orvieto.

In addition to the noble status in Orvieto (1067), where many members of the family held roles such as gonfaloniere, governatore and Signore Sette, the family was co-opted in the nobility of Viterbo (1566), Rome (1518), Fabriano (1686), Todi (1689), Camerino (1691), Loreto (1694) and San Marino (1704).
