Abstract: Using multi-epoch JHKs photometry obtained with the 1.4-m Japanese-South African Infrared Survey Facility at Sutherland we have identified large numbers of AGB variables in NGC 6822. This paper uses 30 large-amplitude variables, with periods ranging from about 200 to 900 days, to provide a new calibration for the period-luminosity relation.
