Mantin is a town in Negeri Sembilan, Malaysia. It is under administration of Nilai District. It lies along the main road connecting Kajang and Seremban.

This place has two names, Setul and Mantin. Setul is the name of certain plant called 'Setul'. Setul was the town with a police station. It is not at the present town of Mantin but at the 8th mile Seremban (junction to Lenggeng). The name Setul is still in use, in grants and licenses of land, e.g. Mukim Setul, not Mukim of Mantin. The town of Setul was transferred to Mantin. The present name of Mantin is well known for its tin mine owned by a Chinese towkay (prominent Chinese businessman), Kong Sang (广生号, actually a company's name). The Europeans called the place 'Mine Tin' while the Malays called it 'Mantin' for at this place tin (lombong timah) was plentiful. The residents of the place could not say 'Mine Tin' correctly and said Mantin instead
