奎师那河（Krishna River，马拉地语︰कृष्णा नदी，卡纳达语︰ಕೃಷ್ಣಾ ನದಿ ，泰卢固语︰కృష్ణా నది）是印度中南部最长的河流之一，河道全长1,400公里。

奎师那河是全球对生态系统造成严重破坏的河流之一，河水湍急且水深达75呎（23米），在6月至8月的季候风季节时间，奎师那河的侵蚀作用把上游肥沃的泥土冲往三角洲地区。

奎师那盆地面积为258,948平方公里，占印度领土的8%。

The Krishna River is the fourth biggest river in terms of water inflows and river basin area in India, after the Ganges, Godavari and Brahmaputra. The river is almost 1,300 kilometres (810 mi) long. The river is also called Krishnaveni. It is a major source of irrigation for Maharashtra, Karnataka, Telangana and Andhra Pradesh.
