Dudley Sargent "Dud" DeGroot (November 10, 1899 – May 5, 1970) was an American athlete and coach, primarily of American football. He served as the head coach for the NFL's Washington Redskins from 1944 and 1945, tallying a mark of 14–5–1; his winning percentage of .737 is the best in franchise history for coaches with at least one full season. DeGroot was also the head football coach at Santa Barbara State College—now the University of California, Santa Barbara (1926–1928), San Jose State University (1932–1939), the University of Rochester (1940–1943), West Virginia University (1948–1949), and the University of New Mexico (1950–1952), compiling a career college football record of 117–67–9. In addition, he served as the head coach of the Los Angeles Dons of the All-America Football Conference from 1946 to 1947.
DeGroot's collegiate participation in sports records that at Stanford University he competed in basketball, football, swimming, and water polo. Playing under the legendary coach, Glenn "Pop" Warner, he became the Stanford Cardinal football team captain in 1922 and their first All-American athlete.
DeGroot's early coaching career included Santa Barbara State College, which is now one of the University of California campuses, and Menlo Junior College, the college level portion of Menlo School which became Menlo College in 1927 and now is independent, although they continue to share the same campus.
From 1932 through 1939, DeGroot was the head football coach at San Jose State University, where he put together a 59–19–8 record for the Spartans. His best season there came in 1939, when his team went undefeated and had outscored opponents 324 to 29. As of 2006 on a list published on Mercury News of the seven biggest turnarounds for a single season in the history of the Spartans, only DeGroot is listed twice, for 1932 and 1937. The statistics for these are: the record for the 1932 season is 7–0–2 with a previous season of 1–7 and a margin of six and, the record for the 1937 season is 11–2–1 with a previous season of 5–4 and another margin of six.
His next team leadership was at the University of Rochester, where he was football coach from 1940 through 1943. DeGroot's record there was 24–6.
Moving to professional sports, he then took over the Washington Redskins, a National Football League (NFL) team, in Washington, D.C. Although they lost the NFL championship for that year by one point, 15–14, to the Cleveland Rams, the Redskins won the Eastern Division title in 1945 with DeGroot as their coach. During two seasons with the Los Angeles Dons of the new All-America Football Conference, DeGroot's record was 14–12–2.
DeGroot returned to collegiate coaching as the head football coach at West Virginia University during 1948 through 1949. His record for the West Virginia Mountaineers was 13–9–1. At the University of New Mexico from 1950 through 1952, DeGroot's record was 13–17 for the Lobos.
