University of Detroit Stadium, also known as U of D Stadium, Titan Stadium, or Dinan Field, was a stadium in Detroit, Michigan on the campus of the University of Detroit. The stadium's main tenant was the University of Detroit Titans football team, who played their home games there from the time the stadium opened in 1922 on land acquired for the university's new McNichols campus (the university would move its main campus there in 1927), until the university dropped the football program following the 1964 season.
The stadium stood on Six Mile Road (later also known as McNichols Road) just west of Fairfield St. in the northeast corner of the campus. It was built with the field on a north-south axis and with stands on the east and west sides of the field, which was encircled by a running track It had a capacity of 25,000 people at its peak. In addition to football, it was also used for track meets, concerts, and other university-related and public events. One rather unusual aspect of the stadium were its lighting towers, which stood between the stands and the field.
University of Detroit Stadium was the home field for the NFL's Detroit Lions from 1934 to 1937, and again in 1940.  It also was home to the Detroit Wolverines for their only NFL season in 1928. It was the site of the 1935 NFL Championship Game, won by the Lions over the New York Giants, 26–7.
The Michigan Arrows of the fledgling Continental Football League used the stadium (which then had a capacity of 20,000) for the 1968 season. Unfortunately, the Arrows drew just 4,240 fans per game en route to a 1-11 season. The Arrows moved to Midland, Michigan to become the Tri-City Apollos in 1969, then folded with the rest of the league.
The stadium was demolished in 1971 and was replaced by a parking lot. For many years thereafter the stadium's lighting towers remained standing in order to provide lighting for the lot.
