Roger Lowell Putnam was an American politician and businessman. A member of the prominent Lowell family of Boston, he served as Mayor of Springfield, Massachusetts, from 1937 until 1943, and as director of the Economic Stabilization Administration from 1951 until 1952. During his short tenure in federal office, the nation's steelworkers struck—leading United States President Harry S. Truman to seize the nation's steel mills.

The Lowell family is one of the Boston Brahmin families of New England, known for both intellectual and commercial achievements.
