We present Two Micron All Sky Survey photometry for 216 symbiotic and possible symbiotic stars. This represents the most comprehensive near‐infrared photometry for these sources which has been published to date. The results are used to define the statistics of S‐ and D‐type stars; to investigate the photometric properties of Magellanic S‐type symbiotics; and to define the possible evolution of D‐type symbiotics within the J − H / H − K S colour plane. It appears that the colours of D‐type symbiotics are consistent with differing mass‐loss rates d M /d t , provided that the grains have a silicate‐like composition, and maximum temperatures of the order of ∼800 K.
