Henry Goddard Leach (July 3, 1880 – November 11, 1970) was an American Scandinavian studies scholar and civic leader.

One summer Leach accompanied the family of a pupil to Scandinavia as a tutor, during which he developed a lifelong fascination for the region.

Leach served as president of the Poetry Society of America from 1934 to 1937, and was rewarded upon his retirement with its medal for having established a fund to aid impoverished poets.

Tall, blue eyed and fair-haired, Leach was often mistaken for a Scandinavian, but was quick to emphasize his English ancestry.

He was married to the former Agnes Lisle Brown, with whom he adopted a son, Jeffrey Eastman Fuller, and a daughter, Annis Leach.
