Adolf Osterwalder (11 March 1872, in Kümmertshausen – 14 March 1961, in Wädenswil) was a Swiss zymologist and wine bacteriologist.

He studied natural sciences at Lausanne and Zürich, receiving his doctorate in 1898 with the dissertation Beiträge zur Embryologie von Aconitum Napellus L ("Contributions to the embryology of Aconitum napellus"). After graduation, he worked as an assistant plant pathologist and fermentation physiologist under Hermann Müller-Thurgau at the experimental institute in Wädenswil. In 1917 he attained the post of deputy director.[1][2]

In 1903, he became a member of the Naturforschenden Gesellschaft in Zürich.[3] Many of his scientific papers were published in the Zentralblatt für Bakteriologie and the Landwirtschaftliches Jahrbuch der Schweiz.[2]
