Jonpuri is considered a janya raga, derived from Natabhairavi (below) which is 20th on the Melakarta Scale.
It is a Hindustani Raga, said to have been named after the sultan Sharqui of Jonpur. It is quite popular in Carnatic music for light classical pieces and folk songs. Even when conveying Bhakti bhava, the raga has a cheerful touch to it. The most popular song in this raga is Eppo Varuvaro by Gopalakrishna Bharathi. You might also have heard Muruganai Bhaji by Papanasam Sivan and Andavan Darishaname by Muttaiah Bhagavathar.
Note : The 12 notes in the octave are named as below. Please note that C is used as Sa for the sake of simplicity as the scale is relative in Carnatic Music. Also note that the scales paint only a superficial picture of the raga as the gamakas(ornamentations) are a very important part of a raga.
