Kajri derived from the Hindi word Kajra, or Kohl, is a genre of semi-classical singing, popular in Uttar Pradesh and Bihar sung by Kajari or 'Kajali' women.

It is often used to describe the longing of a maiden for her lover as the black monsoon cloud come hanging in the summer skies, and the style is notably sung during the rainy season.

It comes in the series of season songs, like Chaiti, Hori and Sawani, and is traditionally sung in the villages and towns of Uttar Pradesh: around Banaras, Mirzapur, Mathura, Allahabad and the Bhojpur regions of Bihar.

Kajree, presented by the women in the group, is called 'Dhunmunis Kajari'. According to the Indian calendar, 'Kadari Teej' festival is celebrated in the entire eastern region by the Bhadrapad month, Krishna Trishya's Trishti. Women on this day fast and Kajri sings through the night. Although the male class also performs Kadri, but their events are different.

Some noted exponents of Kajari are Pandit Channulal Mishra, Shobha Gurtu, Siddheshwari Devi, Girija Devi, Ustad Bismillah Khan, Sharda Sinha and Rajan and Sajan Mishra.
