Chautisa or Chautisha (Odia: ଚଉତିଶା) is a genre of literary composition in Indian literature.
It is a form of constrained writing where each verse begins with consecutive letters of the alphabet, typically starting with the first consonant.
The word 'Chautisa' means thirty four, signifying the number of consonants in Odia script.
The Prachi Samiti (1925–34) collected and published four volumes of medieval poetry and contains hundreds of Chautisas.
Some poets reverse the order of the letters and wrote starting from କ୍ଷ and ends with କ.
