Wilson Homer "Bull" Elkins (July 9, 1908 – March 17, 1994)[1] was an American educator and university administrator.

He was a Rhodes Scholar at Oxford University, where he completed a Ph.D. Elkins served as the president of San Angelo Junior College from 1938 to 1948.

He left San Angelo to become president of Texas Western College in El Paso until beginning his tenure at the University of Maryland in 1954.

In 1957, he created the "Academic Probation Plan," threatening 1,550 students—18 percent of the undergraduate enrollment—with expulsion because their grade point averages were lower than a C. University administration sent 14% of students home, but by 1964, 82% of freshmen came from the top half of their high school classes, and Phi Beta Kappa—which had turned down Maryland twice before—had established a chapter on campus.

Elkins supported the establishment of a faculty government and managed a major expansion and improvement of the physical plant, including the construction of the McKeldin Library and the Computer Science Center.
