John W. Davis, American lawyer and politician, 14th United States Solicitor General (d. 1955)
John William Davis (April 13, 1873 – March 24, 1955) was an American politician, diplomat and lawyer. He served under President Woodrow Wilson as the Solicitor General of the United States and the United States Ambassador to the United Kingdom. He was the Democratic nominee for president in 1924 but lost to Republican incumbent Calvin Coolidge.

Born and raised in West Virginia, Davis briefly worked as a teacher before beginning his long legal career. Davis's father, John J. Davis, had been a delegate to the Wheeling Convention and served in Congress in the 1870s. Davis joined his father's legal practice and adopted many of his father's political views, including opposition to anti-lynching legislation and support for states' rights. Davis served in the United States House of Representatives from 1911 to 1913, helping to write the Clayton Antitrust Act. He held the position of solicitor general in the Justice Department from 1913 to 1918, during which time he successfully argued for the unconstitutionality of Oklahoma's "grandfather law" in Guinn v. United States, which had a discriminatory effect against African American voters.

While serving as the ambassador to Britain from 1918 to 1921, Davis was a dark horse candidate for the 1920 Democratic presidential nomination. After he left office, Davis helped establish the Council on Foreign Relations and advocated for the repeal of Prohibition. The 1924 Democratic National Convention nominated Davis for president after 103 ballots. Davis remains the only major party presidential candidate from West Virginia. Running on a ticket with Charles W. Bryan, Davis lost in a landslide to incumbent President Coolidge.

Davis did not seek public office again after 1924. He continued as a prominent attorney, representing many of the country's largest businesses. Over a 60-year legal career, he argued 140 cases before the United States Supreme Court. He notably argued the winning side in Youngstown Sheet & Tube Co. v. Sawyer, in which the Supreme Court ruled against President Harry Truman's seizure of the nation's steel plants. Davis unsuccessfully defended the "separate but equal" doctrine in Briggs v. Elliott, one of the companion cases to Brown v. Board of Education, in which the Court ruled in 1954 that segregated public schools were unconstitutional.
