Malin Kundang, Si Tanggang also called Nakhoda Manis, is a Southeast Asian folktale about retribution on an ungrateful son. A sailor from a poor family, the protagonist sneaks onto a trading ship, eventually becoming rich, marrying a princess, and acquiring his own galleon. On his return to his home village, he is ashamed of his humble origins and refuses to recognise his elderly mother. It is because the rich man saw his elderly mother was dirty and poor. She curses him, and when he sets sail, he and his ship are turned to stone.
In Indonesia, the story is called Malin Kundang, and the legend is based in West Sumatra. Air Manis, a beach near Padang, has a rock formation called Batu Malin Kundang that is said to be the remains of his ship.
Another Indonesian folk story which is alike but take the different location is the legend of Sampuraga. The legend is based in Central Borneo. Belantikan Hulu, a remote area along the river Lamandau, Indonesia, has a rock formation called Bukit Sampuraga which is believed to be the ruins of his ship.
In Brunei, the story is Nakhoda Manis and is associated with a prow-like rock, Jong Batu, in the Brunei River.
In Malaysia and Singapore, the story is known as Si Tenggang or Si Tanggang, being associated with the Batu Caves, some chambers of which are said to resemble a ship's cabins.

As a parable on family responsibility, the story is popular in Southeast Asia as a theme for animations, film, drama and literature even until today. For example:
