William Carey Richards (November 24, 1818 – May 19, 1892) was an American magazine editor, author, and Baptist minister, known for his contributions to literature and magazines of the Southern United States during the 19th century.

Richards was born in London, England on November 24, 1818, to William Richards, a Baptist minister, and Anne Gardener Richards. Richards immigrated to the United States in 1831 with his family, settling initially in New York City, where his father became the minister of a church in Hudson, before the rest of the family relocated to Penfield, Georgia.

Richards stayed in New York and attended Colgate University (then called Madison University), before graduating and moving to Penfield in 1840. In 1841, Richards married Cornelia Richards (née Bradley), also a writer, having met her in New York.

Richards began professionally writing with contributions to the Augusta Mirror, a literary paper published between 1838 and 1841. He later contributed to various periodicals, including the Southern Ladies' Book and Family Companion (Macon, Georgia), the Southern Quarterly Review (Charleston, South Carolina), the Christian Review (Boston, Massachusetts) and The Knickerbocker (New York).

In the 1840s, Richards started his own publications, beginning with the Orion, a literary magazine aimed at fostering literature in the South. This was named after the Orion constellation. Orion featured works by prominent Southern writers of the time, including William Gilmore Simms, as well as well-known Northern writers.

He later founded the Southern Literary Gazette (Athens, Georgia) and the educational magazine Schoolfellow (Athens).

In the 1850s, Richards shifted his focus to the ministry, serving pastorates in Massachusetts, Rhode Island and Illinois until his death. He continued to write, mainly on religious topics and physical science, popularising these subjects through his lectures in the United States and Canada.

He died on May 19, 1892, at the age of 73 in Chicago.
