John Phillip White (February 28, 1870 – September 21, 1934) was a miner and president of the United Mine Workers of America (UMWA) from 1911 to 1917.

He was born in Coal Valley, Rock Island County, Illinois in 1870 and went to work in the mines as a teenager before moving with his family to Iowa.

He won UMWA approval of the six-hour day, a ban on the employment of anyone under the age of 16, pensions, and workers' compensation.

Although he was a political conservative, he forced through an amendment to the UMWA constitution forbidding membership in the National Civic Federation.

In 1912, he forced delegates of the UMWA convention to approve a resolution asking the American Federation of Labor to endorse industrial unionism.
