John Henry Ray (September 27, 1886 – May 21, 1975) was an American lawyer, business executive, and politician who served as a U.S. Representative from New York as a member of the Republican Party.

He served five terms in Congress representing the state's 15th district, which at the time encompassed parts of Staten Island and Brooklyn.

He joined the U.S. Army during World War I, serving first as a first lieutenant in the Judge Advocate General's Corps, and then an assistant to the special representative of Secretary of War Newton D. Baker during post-war armistice discussions with Allied governments.

He sought the establishment of tax-free pensions, and to give tax breaks to firms purchasing anti-pollution equipment.

He chose to retire rather than seek reelection in the new constituency in 1962; that year, his seat was won by Democrat John Murphy.
