|Coaching career (HC unless noted)|
|Head coaching record|
Oscar J. Dahlene was a college football player and coach from the United States. He would later become the eighth president of Pritchett College in Glasgow, Missouri from 1917 until 1920. He died in 1949 in Alabama.
As of the completion of the 2007 season, 1908 was the last season that the school would have finished the season undefeated and untied. KU was the undisputed Missouri Valley Conference champions and finished with a record of 9 wins, zero losses, and zero ties. As a kicker, he was the only player to score in the first half of the Nebraska game in 1908, scoring 16 points. Kansas won the game by a score of 20-15, thus making Dahlene's 16 points critical to their undefeated 9-0 season and conference title.
After graduation from the University of Kansas, Dahlene would be named the fourth head college football coach for the Ottawa University Braves located in Ottawa, Kansas and he held that position for the 1910 season. His career coaching record at Ottawa was 2 wins, 3 losses, and 1 tie. This ranks him 24th at Ottawa in total wins and 20th at Ottawa in winning percentage (0.333).  During his one season as head coach, he was outscored by one point: 29 points to 30.
Dahlene's first game as a head coach was against his former mentor, A. R. Kennedy from the University of Kansas.
