Kasimedu is a hamlet in the neighbourhood of Royapuram, in Chennai district of Tamil Nadu state in the peninsular India. This hamlet is occupied by fishermen whose families depend on the fishing harbour and the fish market nearby. It stretches for about 2 km, near Ennore fishing harbour along the shore, north of Chennai Port. [1] Large numbers of victims from Kasimedu fishing community were found during the tsunami observed on 26 December 2004. Kasimedu is located at about 5 km from Chennai Beach railway station. Near about 200 tons of fishes are brought to Kasimedu, daily.[2] State Highway 114 (Ennore Express road) passes through Kasimedu.

Ramachandran, in the year 1975.[6] This harbour will be upgraded by the government of India, to international standards with a project cost of ₹98 crore.[7] About 1,000 mechanised fishing boats are available in Kasimedu.[8]
