The Indian spin quartet is the collective name given to the Indian cricket spin bowlers of the 1960s and 1970s: Erapalli Prasanna and Srinivas Venkataraghavan (both off spinners), Bhagwat Chandrasekhar (a leg spinner), and Bishen Singh Bedi (a left-arm spinner). Among them, they played 231 Test matches, taking 853 wickets. They were one of the most deadly combinations in world cricket, especially on the dusty subcontinental pitches.
The spin quartet was instrumental in producing many Indian Test victories. There was only one match in which all four of them were in the starting XI: usually one of the off spinners, Prasanna or Venkataraghavan, was left out. However, these four men made important contributions to some of India's greatest triumphs, including Test series victories in the West Indies and England, as well as Test victories in Australia and New Zealand.
In 2004, the Board of Control for Cricket in India conferred on them the CK Nayudu award, named after India's first Test captain.
