The Istana Ampang Tinggi was a royal residence in Negeri Sembilan in Malaysia.
The palace was built without using any nails with a length of 66.5 feet and 23.5 feet width. It was ordered by Yamtuan Imamg, the 5th Yang di Pertuan Besar of Negeri Sembilan. The palace was built between 1865 and 1870 at Ampang Tinggi ("High Dam") in Kuala Pilah on a ridge overlooking a wide expanse of paddy fields.
When it was completed the, the ruler gave it to his daughter Puteri Cindai, when she married Tengku Muda Chik, the son of the 4th Yamtuan Radin. The palace stood six miles from Seri Menanti when in 1953 the 8th Yamtuam Tuanku Abdul Rahman gave permission for the istana to be dismantled and transported to Seremban to its current location in 1980 about three miles from Seremban. Today, it serves as a small museum containing weapons and other historical artifacts from Negeri Sembilan.
