Adolphus Wolgast (February 8, 1888 – April 14, 1955), nicknamed Michigan Wildcat, was the world's lightweight champion from 1910 to 1912.

He was fond of eating steak and opposed the vegetarian diet of rival lightweight boxing champion Freddie Welsh.

[4] He turned professional in 1906, and on February 22, 1910 he won the World Lightweight Title with a technical knockout (TKO) during a 40-round bout with Battling Nelson.

Wolgast would later defend the title against Mexican Joe Rivers in 1912, a bout that caused controversy.

In December 1918 a Los Angeles court found him competent to handle his own affairs, and terminated the guardianship.
