Dukinfield Henry Scott FRS (November 28, 1854 – January 29, 1934) was a British botanist.
The architect Sir George Gilbert Scott was his father. Born in London, he was educated at Oxford University (awarded MA) and Wurzburg University (awarded PhD), studying under the famous botanist Julius von Sachs.

In 1892, Scott left the Royal College of Science when he was appointed Honorary Keeper of the Jodrell Laboratory, Royal Gardens at Kew, a position he held for fourteen years. He published many papers on botany in scientific journals. He did important work in paleobotany as the younger colleague of William Crawford Williamson, one of the founders of paleobotany.
He was president of the Linnean Society from 1908 to 1912. He was elected a member of the Royal Swedish Academy of Sciences in 1916 and a Fellow of the Royal Society in June 1894.

He died in East Oakley House near Basingstoke, Hants. He had married Henderina Victoria Klaassen in 1887; they had six children. One of his most brilliant students was Harold Wager, who became his student in botany in 1886 and went on to become F.R.S in 1904.
