Saraiki ( سرائیکی Sarā'īkī, also spelt Siraiki, or Seraiki) is an Indo-Aryan language of the Lahnda group, spoken in the south-western half of the province of Punjab in Pakistan. It was previously known as Multani, after its main dialect.

Saraiki is to a high degree mutually intelligible with Standard Punjabi and shares with it a large portion of its vocabulary and morphology. At the same time in its phonology it is radically different (particularly in the lack of tones, the preservation of the voiced aspirates and the development of implosive consonants), and has important grammatical features in common with the Sindhi language spoken to the south.
