Francis March was a late 19th and early 20th century polymath, who lived in Pennsylvania, USA. He taught a wide range of subjects at Lafayette College, and published a once well-known thesaurus in 1902. He was the first American superintendent over the volunteer reading programme of the Oxford English Dictionary.

March is known to have published learned books from at least 1870 and amongst other subjects taught botany, French, German, Greek, Latin, 'mental philosopy', 'political economy' and law.

He is a largely forgotten figure, his thesaurus is no longer available, and he is not mentioned by Britannica or by the American National Biography .
