Harry Smith FRS (September 19, 1935 – February 9, 2015) was a British botanist. Smith is best known for his discovery that phytochromes can detect changes in the colour that plants receive (e.g., because of shading from neighbouring plants), which allows them to adjust their growth rates accordingly. Smith was the founding editor of the academic journal Molecular Ecology, and its managing editor from 1992 to 2008. He was also the founding editor of the journals Molecular Ecology Resources, Global Change Biology, and Plant, Cell & Environment. In 2000, Smith was elected as a Fellow of the Royal Society.
