Raina II (also spelled Rayna and called Rainagar) is a community development block that forms an administrative division in the Bardhaman Sadar South subdivision of the Purba Bardhaman district in the Indian state of West Bengal.
 In 1933, independence activist Dasarathi Tah was involved in Swadeshi dacoities in Meral, Mirzapur and Bogra in the area. Damodar floods wrought havoc in the area and Dasarathi Tah initiated the ‘Nakrah hana embankment movement’ and even published a weekly newspaper named Damodar to focus on the problems faced by the people. In 1948, Raina witnessed the ‘Tebhaga movement’, where sharecroppers demanded a higher share of the crops they grew. The movement was led by Benoy Choudhury and Bipadtaran Roy. Great revolutionary Rashbehari Bose was born in village-Subaldaha, Block-Raina 2, Dist-Purba Bardhaman, West Bengal.
