Aberdalgie (Gaelic: Obar Dheilgidh, 'Confluence of the Thorn-Stream') is a village in the Scottish council area of Perth and Kinross. It is located 4 kilometres (2.5 mi) southwest of Perth, to the south of the B9112 road in Strathearn.
In the Aberdalgie Churchyard (formerly inside the church before that moved) is the family vault where Medieval heads of Clan Oliphant are buried. Prominent among them is Sir William Oliphant, the resolute Governor of Stirling Castle when in 1304 it held out longer than any other against Edward I of England, during the Wars of Scottish Independence. Also buried there are Sir William's son, Sir Walter Oliphant, and his wife, Princess Elizabeth, the youngest daughter of King Robert the Bruce.
The tomb was covered by an effigy which is the finest example of Tournai stone work in Scotland. From the design of the armour of the recumbent figure of the effigy, it has been dated to around 1365, which was some long time after Sir William died but fits most closely with the dates of Sir Walter and his Royal bride. The tomb is now the registered lair of the Chief of Clan Oliphant.
