William Ripley Nichols (April 30, 1847 – July 14, 1886) was a noted American chemist.

Nichols was born in Boston, Massachusetts, graduated from the Massachusetts Institute of Technology in 1869, and served there as instructor and assistant professor until 1872, when he was elected professor of general chemistry, which chair he retained until his death in Hamburg, Germany.

Professor Nichols was recognized as an authority on sanitation, and particularly on water purification, published numerous papers on municipal water supplies, and was active in the pioneering work of the Lawrence Experiment Station. He also performed research at the request of the Massachusetts Board of Health on train ventilation, particularly of smoking cars. He was a member of the American Academy of Arts and Sciences, the American Association for the Advancement of Science, of which he was Vice President in 1885, and of the German Chemical Society.
