Cal R. Ludeman (/ˈluːdəmən/ LOO-də-mən; born April 1951) is an American politician who most recently served as Secretary of the Minnesota Senate.

He served on the House Agriculture, Environment & Natural Resources, Government Operation, Labor-Management Relations, and Transportation committees, and on various sub-committees relevant to each area.

[2] After Governor Pawlenty left office in January 2011, Ludemann was selected to serve as Secretary of the Minnesota Senate by the incoming Republican majority.

"[6] On May 25, 2012, the Minnesota Senate released legal bills showing they had spent $46,150 in the first 3 months of 2012 to prepare a defense to Brodkorb's suit.

[7] An analysis of the bill by the Associated Press showed the bulk of the $46,150 owed was due to attorneys retained by the Minnesota Senate repeatedly meeting with Ludeman.
