Julius Wechselberg (March 9, 1838 – May 17, 1924) was a German American immigrant, carriage maker, lawyer, real estate broker, and Republican politician.

Wechselberg was born in Barmen in the Rhine Province of the Kingdom of Prussia on March 9, 1838, and came to Wisconsin with his parents in 1848 (his father did not want his sons to be conscripted into the Prussian Army).

He received a common school and commercial education, and settled at Milwaukee, where he first went to work for a carriage maker at a salary of $30 a year (plus board).

Wechselberg was alderman of his ward from 1872 to 1876, and was then elected clerk of circuit court of Milwaukee County, serving from 1877 to 1883; during this period, he studied law and became an attorney.

In 1892, Wechselberg was the Republican nominee for United States House of Representatives from Wisconsin's 5th congressional district, losing to Democratic incumbent George Brickner due to Brickner's margins in the portions of the district outside Milwaukee County.
