Bryan elicited mixed views during his lifetime and his legacy remains complicated.
Author Scott Farris argues that "many fail to understand Bryan because he occupies a rare space in society ... too liberal for today's religious [and] too religious for today's liberals."
Jeff Taylor rejects the view that Bryan was a "pioneer of the welfare state" and a "forerunner of the New Deal," but argues that Bryan was more accepting of an interventionist federal government than his Democratic predecessors had been.
Biographer Michael Kazin, however, opines that
Bryan was the first leader of a major party to argue for permanently expanding the power of the federal government to serve the welfare of ordinary Americans from the working and middle classes ... he did more than any other man—between the fall of Grover Cleveland and the election of Woodrow Wilson—to transform his party from a bulwark of laissez-faire to the citadel of liberalism we identify with Franklin D. Roosevelt and his ideological descendants.

Kazin argues that, compared to Bryan, "only Theodore Roosevelt and Woodrow Wilson had a greater impact on politics and political culture during the era of reform that began in the mid-1890s and lasted until the early 1920s."
Writing in 1931, former Secretary of the Treasury William Gibbs McAdoo stated that "with the exception of the men who have occupied the White House, Bryan ... had more to do with the shaping of the public policies of the last forty years than any other American citizen."
Historian Robert D. Johnston notes that Bryan was "arguably [the] most influential politician from the Great Plains."
In 2015, political scientist Michael G. Miller and historian Ken Owen ranked Bryan as one of the four most influential American politicians who never served as president, alongside Alexander Hamilton, Henry Clay and John C. Calhoun.

Kazin also emphasizes the limits of Bryan's influence, noting that "for decades after [Bryan]'s death, influential scholars and journalists depicted him as a self-righteous simpleton who longed to preserve an age that had already passed."
Writing in 2006, editor Richard Lingeman noted that "William Jennings Bryan is mainly remembered as the fanatical old fool Fredric March played in Inherit the Wind."
Similarly, in 2011, John McDermott wrote that "Bryan is perhaps best known as the sweaty crank of a lawyer who represented Tennessee in the Scopes trial.
After his defence of creationism, he became a mocked caricature, a sweaty possessor of avoirdupois, bereft of bombast."
Kazin writes that "scholars have increasingly warmed to Bryan's motives, if not his actions" in the Scopes Trial, due to Bryan's rejection of eugenics, a practice that many evolutionists of the 1920s favored.

Kazin also notes the stain that Bryan's acceptance of the Jim Crow system places on his legacy, writing
His one great flaw was to support, with a studied lack of reflection, the abusive system of Jim Crow—a view that was shared, until the late 1930s, by nearly every white Democrat ... After Bryan's death in 1925, most intellectuals and activists on the broad left rejected the amalgam that had inspired him: a strict populist morality based on a close read reading of Scripture ... Liberals and radicals from the age of FDR to the present have tended to scorn that credo as naïve and bigoted, a remnant of an era of white Protestant supremacy that has, or should have, passed.

Nonetheless, prominent individuals from both parties have praised Bryan and his legacy.
In 1962, former President Harry Truman said Bryan "was a great one—one of the greatest."
 Truman also claimed: "If it wasn't for old Bill Bryan, there wouldn't be any liberalism at all in the country now.
Bryan kept liberalism alive, he kept it going."
Tom L. Johnson, the progressive mayor of Cleveland, Ohio, referred to Bryan's campaign in 1896 as "the first great struggle of the masses in our country against the privileged classes."
In a 1934 speech dedicating a memorial to Bryan, President Franklin D. Roosevelt said
I think that we would choose the word 'sincerity' as fi
