Littoinen is a village in south-western Finland, centred on Lake Littoinen (Finnish: Littoistenjärvi). The village is shared between the town of Kaarina and the municipality of Lieto, and it borders the regional centre of Turku. It started growing after the founding of a broadcloth factory by Lake Littoinen in 1739, and the railway connection built in 1899 increased its growth. In the 1960s the operations of the broadcloth factory (Finnish: verkatehdas) were discontinued due to decreased demand, but the premises still exist and have been transformed into residential and commercial spaces.
