Kondaikatti Vellalar is a Tamil caste who traditionally pursued agriculture as a profession in the Indian states of Tamil Nadu, Kerala and northeastern parts of Srilanka. They are part of the larger Saiva Vellalar social group of people. They were originally settled in Tondaimandalam but spread to other areas in south India over time. Since they historically used the Mudaliar title, they are sometimes referred to as Thondaimandala Vellala Mudaliars or simply Thondaimandala Mudali. However, Kathleen Gough considers them to be a separate subcaste of the Thondaimandala Mudali, as does Susan Neild.
