Jana Ranjani is a raga in Carnatic music, the classical music of South India. It is a janya raga of Shankarabharanam, the 29th of the 72 melakarta ragas. The raga is named thus because it induces a feeling of enjoyment (Jana – People and Ranjani – can be enjoyed by people) among the rasikas (audience).
