Nehr-e-Khayyam (Urdu: نہر خیام), situated in Clifton, Karachi, Pakistan, is a water channel originally constructed as a storm drain.

Despite its original purpose of draining rainwater into the sea, and first plans as a 'recreational zone' in the 1970s,[3] Nehr-e-Khayyam has, over the decades, become a focal point of urban interest for environmental reasons.

[4] The channel is plagued by heavy pollution, filled with garbage and sewage, a stark contrast to its location in the densely populated and upscale neighbourhood of Clifton.

[7][8] However, these endeavors have been marred by challenges such as broken contracts, unclear responsibilities, and financial discrepancies, resulting in unresolved legal disputes awaiting adjudication in courts.

[9][10] Beyond issues of pollution and degraded water quality, scientific studies have highlighted the pervasive presence of bacteria within the channel, all of which eventually flow through the Chinna Creek into the Arabian Sea.
