Mohanakalyani is a rāgam in Carnatic music (musical scale of South Indian classical music). It is a janya rāgam (derived scale) from the 65th melakarta scale Mechakalyani. It is a janya scale, as it does not have all the seven swaras (musical notes) in the ascending scale. It is a combination of the pentatonic scale Mohanam and the sampurna raga scale Kalyani.
The equivalent of Mohanakalyani in Hindustani music is Bhoop Kalyan or Shuddha Kalyan. Bhoop Kalyan belongs to the Kalyan thaat of Hindustani music. Similar to Mohanakalyani, Bhoop Kalyan is a combination of Bhoop and Kalyan.

The notes used in this scale are shadjam, chathusruthi rishabham, antara gandharam, panchamam and chathusruthi dhaivatham in ascending scale, with kakali nishadham and prati madhyamam included in descending scale. For the details of the notations and terms, see swaras in Carnatic music.
