Max Ehrmann (September 26, 1872 – September 9, 1945) was an American writer, poet, and attorney from Terre Haute, Indiana, widely known for his 1927 prose poem "Desiderata" (Latin: "things desired"). He often wrote on spiritual themes.

Ehrmann was of German descent; both his parents emigrated from Bavaria to the United States in the 1840s. Young Ehrmann was educated at the Terre Haute Fourth District School and the German Methodist Church.

He received a degree in English from DePauw University in Greencastle, Indiana, which he attended from 1890 to 1894. While there, he was a member of Delta Tau Delta's Beta Beta chapter and was editor of the school newspaper, Depauw Weekly.

Ehrmann then studied philosophy and law at Harvard University, where he was editor of Delta Tau Delta's national magazine The Rainbow, circa 1896.

Ehrmann returned to his hometown of Terre Haute, Indiana, in 1898 to practice law. He was a deputy state's attorney in Vigo County, Indiana, for two years. Subsequently, he worked in his family's meatpacking business and in the overalls manufacturing industry (Ehrmann Manufacturing Co.) At age 40, Ehrmann left the business to write. At age 55, he wrote Desiderata, which achieved fame only after his death.

Ehrmann was awarded Doctor of Letters honorary degree from DePauw University in about 1937. He was also elected to the Delta Tau Delta Distinguished Service Chapter, the fraternity's highest alumni award.

Ehrmann died in 1945 and is buried in Highland Lawn Cemetery in Terre Haute, Indiana.

In 2010 the city honored Ehrmann with a life-size bronze statue by sculptor Bill Wolfe. He is depicted sitting on a downtown bench, pen in hand, with a notebook in his lap. "Desiderata" is engraved on a plaque next to the statue and lines from the poem are embedded in the walkway. The sculpture is in the collection of Art Spaces, Inc. – Wabash Valley Outdoor Sculpture Collection. Art Spaces also holds an annual Max Ehrmann Poetry Competition.
