John Esten Miles (born July 28, 1884) was a Democratic politician who represented the state of New Mexico in the United States House of Representatives. Serving as an at-large Representative, he held office for a single term from January 3, 1949, to January 3, 1951. His tenure places him among the historical members of Congress from New Mexico in the mid-twentieth century.

During his time in the House, Miles served as a member of the Democratic Party, representing all of New Mexico rather than a specific numbered district, as indicated by his at-large designation. His congressional service lasted one term, and he did not return to office after 1951. Further details about his committee assignments, office contact information, or subsequent public roles are not provided in the available record.
