Frank Augustus Miller (June 30, 1858 – June 17, 1935) was the owner and chief developer of the Mission Inn in Riverside, California, United States, where Frank Augustus Miller Middle School was named after him. He was also a civic leader and one of Riverside's strongest promoters.

Frank Miller was born in Tomah, Wisconsin in 1857 to Christopher Columbus "CC" Miller and Maryanne Miller, one of four children. CC Miller brought his family to Riverside in 1874. As a surveyor and civil engineer CC was a respected and valuable contributor to the development of Riverside. He paid $250 cash for a one square block parcel of downtown Riverside. He and his family built a home of which the first floor was adobe bricks and the second floor was wood-frame construction. They did not like the appearance of the adobe building and drew upon their Midwest values to cover it in wooden clapboards. The 12 room structure had originally been planned as a home for the Miller family with extra rooms for boarders, since there were no hostelries available for visitors.

Both of Frank Miller's parents had college degrees and they wanted to send him to a college in Ohio. He pleaded with them stating that he really wasn't a good student anyway and he would live an exemplary life if they would let him stay in Riverside and run the hotel. His parents assented and Maryanne made arrangements for the only teacher in town, Isabella Hardenberg, to tutor her son, Frank. Isabella was already a boarder at the Glenwood Inn. After months of tutoring, Frank and Isabella hit it off and married in 1880. Since CC did not like managing the boarding house, he later sold it and the property to Frank for $5K.
 
In 1902 Frank Miller and his architect Arthur Benton built "the Mission Wing", a U-shaped structure in 'Mission Revival' style of 84 new rooms as the first major expansion to the Mission Inn. He garnered $250,000 in financial support from his friend, Henry Huntington.
In 1911 the Cloister Wing was built by architect Arthur Benton.
In 1914 the Spanish Wing was completed (of which the first three floors were designed by architect Myron Hunt, who also designed the
Rose Bowl, Huntington Library and the First Congregational Church in Riverside). 
In 1931 the Rotunda Wing by architect G Stanley Wilson was completed.

Some of Frank Miller's accomplishments include:
	started a trolley service from the Mission Inn Hotel to Arlington along Magnolia Blvd
	opened the "Blue Front Grocery" named for the bright blue paint on the front of the store
	managed the 1,000 seat Loring Opera House including arranging for the entertainers

	started the Mount Rubidoux Easter Sunrise Service in 1909 which still occurs every Easter
	was a founding member of the County of Riverside when it formed from portions of San Diego and San Bernardino Counties
	helped arrange for the Federal Government to locate a military airfield, March Field, adjacent to Riverside now known as March Field Air Reserve Base
	was influential in arranging for a Citrus Testing Station to help citrus growers optimize procedures and defend their crops from diseases.  The Citrus Testing Station ultimately became the University of California, Riverside, aka UCR, which had 22,000 students in 2016

He is buried in Riverside's Evergreen Cemetery.
