	Ardstinchar Castle is a late medieval castle in the west coast of Ayrshire at the mouth of the River Stinchar. It was built by Hugh Kennedy of Ardstinchar in the mid-15th century. In the 1770s, the castle was demolished and the stone was used to build a bridge over the River Stinchar. Only remnants of the castle keep remain to this day. The site is a scheduled monument.
