Alfred Armand Adolf von Steiger, commonly known as Adolf von Steiger (25 July 1859 – 1 March 1925) was a Swiss Politician from the Free Democratic Party of Switzerland (FDP) and jurist, who served as the sixth Chancellor from 1919 to 1925.

The son of a librarian from an old Bernese patrician family, he studied law at the Universities of Bern, Geneva, and Leipzig.

After two years as a substitute judge, he was a member of the Bernese court from 1893.

He stood up to the Catholic conservative Solothurn National Council and Siegfried Hartmann.

On taking office he also passed a new law that relieved the Chancellor of the record keeping in the National Council.
