Arumanai or Arumana is a Panchayat town in Kanyakumari district in the state of Tamil Nadu, India. In olden days it is known as Arumana. The plot of critically acclaimed Malayalam language movie Ozhimuri is set in the background of Arumanai.

The town and its surroundings are very fertile and all species of flora of the West Coast grow here. However, the introduction of rubber cultivation in the hilly and semi-hilly areas of the district in the 1950s had marked a change in the utilization of the cultivable lands. Now rubber is raised as the main agricultural crop in almost all the villages and panchayat towns of Vilavancode taluk and Kalkulam taluks of the district.
