Maurice Joseph Tobin (May 22, 1901 – July 19, 1953) was an American politician serving as 46th Mayor of Boston, the 56th Governor of Massachusetts and 6th United States Secretary of Labor.

Deeply rooted in the highly politicized Irish Catholic community, he was the oldest of four children of James Tobin, a carpenter, and Margaret Daly.

He took evening classes[5] at Boston College and worked for Conway Leather and New England Telephone before entering politics as a protégé of the legendary James Michael Curley.

[citation needed] He was fiscally conservative, choosing to forgo the large public works projects that had characterized the Curley administration, and he smoothed over previously contentious battles with the federal government over access to New Deal relief funding.

[12][6] Governor Tobin remained active in Democratic politics, however, and campaigned vigorously for President Truman in 1948.

Tobin repeatedly denounced the Taft-Hartley Act of 1947, making 150 speeches against it in the 1948 election campaign.

Although the Democrats regained control of Congress in 1948 election, the Conservatives were still dominant and Tobin and Truman were unable to repeal Taft-Hartley.

"[13] Shortly after he left his position in the Truman cabinet in January 1953, Tobin died of a heart attack on July 19, 1953, at his summer home in Scituate, Massachusetts, at the age of 52.

An elementary school is named after Tobin in the Mission Hill neighborhood of Boston, where he was born.
