Suriyani Malayalam (സുറിയാനി മലയാളം, ܣܘܪܝܢܝ ܡܠܝܠܡ), also known as Karshoni, Syro-Malabarica or Syriac Malayalam, is a dialect of Malayalam written in a variant form of the Syriac alphabet which was popular among the Saint Thomas Christians (also known as Syrian Christians or Nasranis) of Kerala in India. It uses Malayalam grammar, the Maḏnḥāyā or "Eastern" Syriac script with special orthographic features, and vocabulary from Malayalam and East Syriac. This originated in the South Indian region of the Malabar Coast (modern-day Kerala). Until the 19th century, the script was widely used by Syrian Christians in Kerala.

There were numerous problems in writing Malayalam using the Syriac script, which was designed for a Semitic language. Only 22 letters were available from the East Syriac alphabet to render 53 or so phonemes of Malayalam. This problem were overcome by adopting letters from the Malayalam script.
