John Joseph Enneking (October 4, 1841 – November 16, 1916) was an American Impressionist painter associated with the Boston School.

[2] He was educated at Mount St. Mary's College, Cincinnati, served in the American Civil War in 1861–1862, studied art in New York and Boston, and gave it up because his eyes were weak, only to return to it after failing in the manufacture of tinware.

Enneking is a plein air painter, and his favorite subject is the November twilight of New England, and more generally the half lights of early spring, late autumn, and winter dawn and evening.

Over 1,000 people attended the 1915 event and Enneking was crowned with the victor's laurel wreath by the prominent sculptor Cyrus Dallin.

[5] Shortly after his death, memorial exhibitions of his work were held at the Boston Art Club and in Portland, Maine.
