Frederick Arthur "Dutch" Lamlein (August 14, 1887 – September 20, 1970) was a pitcher in Major League Baseball.

Lamlein was often misspelled "Lamline" on baseball cards, programs, and newspaper print items throughout his minor and major league careers.

Lamlein is also credited with moving the North American Silverstick Championship Finals youth hockey tournament to his hometown in Port Huron, MI in 1963.

To this day, Port Huron is still the site of this annual tournament which brings the top youth travel hockey teams from all over North America to compete for the Silverstick award.
