Minyak Beku is a mukim in Batu Pahat District, Johor, Malaysia.
The big rock was chiselled by the Siamese (Ayudhya) to contain fresh water.
It was said that the Siamese soldiers came here by boat to attack Malacca but were defeated by Tun Perak in the 15th century.
The chiselled rock became famous where it later replaced the name of Bandar Penggaram to Batu Pahat.
The road from Batu Pahat town ends abruptly at Kampung Minyak Beku.
