Haworth is commemorated at the University of Birmingham in the Haworth Building, which houses most of the University of Birmingham School of Chemistry. The School has a Haworth Chair of Chemistry, held by Professor Nigel Simpkins from 2007 until his retirement in 2017, and by [https://www.birmingham.ac.uk/staff/profiles/chemistry/professor-neil-champness.aspx Professor Neil Champness]  since 2021.
In 1977 the Royal Mail issued a postage stamp (one of a series of four) featuring Haworth's achievement in synthesising vitamin C and his Nobel prize.
He also developed a simple method of representing on paper the three-dimensional structure of sugars.  The representation, using perspective, now known as a Haworth projection, is still widely used in biochemistry.
