Henry Payne “Hank” Iba (/ˈaɪbə/; August 6, 1904 – January 15, 1993) was an American basketball coach and college athletics administrator.

As head coach of the United States men's national basketball team, he led the U.S. to the gold medals at the 1964 and 1968 Summer Olympics.

Iba's "swinging gate" defense (a man-to-man with team flow) was applauded by many, and is still effective in today's game.

His 1945 champions defeated National Invitation Tournament champion, DePaul, and 6'10" center George Mikan in a classic Red Cross Benefit game.A&M/State teams won 14 Missouri Valley titles and one Big Eight title, and won 655 games in 36 seasons.

That year, the Cowboys joined (or rejoined, depending on the source) the Big Eight and promptly won the conference title, advancing all the way to the Elite Eight.

All told, in 40 years of coaching, he won 767 games—the second-most in college basketball history at the time of his retirement.

As OSU's athletic director, he built a program that won 19 national championships in 5 sports (basketball, wrestling, baseball, golf, cross-country) over the years.

After his retirement, "Mr. Iba" (as he is still called at OSU) frequently showed up at practices, often giving advice to young players.

Iba was indirectly responsible for a $165 million donation to the Oklahoma State University athletic program.

Iba set the young graduate up with two interviews for high-school basketball coaching jobs and although Pickens didn't end up becoming a coach, the favor Iba did for him was the impetus behind his decision 50 years later to make a $165 million donation to Oklahoma State University's athletic program.

Coaches in this tree typically use a physical man-to-man defense and an offense predicated on ball movement and passing.
