Frederick Tennyson Congdon (November 16, 1858 – March 13, 1932) was a Canadian politician, lawyer, and served as the fourth commissioner of Yukon.

Congdon was born in Annapolis, Nova Scotia and attended Yarmouth High School.

His term in office was not looked upon with a positive feeling and it was mired by corruption and controversy.

Only a year after his appointment, Congdon resigned so he could win the Yukon's seat in the House of Commons of Canada, which had been recently vacated by former Yukon Commissioner James Hamilton Ross, who left his seat when he was appointed to the Senate of Canada.

A loyal Liberal Party member, Congdon was defeated for the seat in Parliament.
