Nicholas "Nick" Kropfelder (February 19, 1923 - August 4, 2012) was an American soccer center forward.
Kropfelder grew up in Baltimore where he played baseball, basketball, and soccer at Mount Saint Joseph College, a secondary school, from 1938 to 1940.
From September to November 1941, he went on trial with Baltimore SC of the American Soccer League, but returned to Santa Maria as it made a run to the semifinals of the 1942 National Amateur Cup.
In 1943, Kropfelder's career was interrupted by military service during World War II and he didn't return to the Americans until 1946.
After retiring from playing professionally, Kropfelder served as both an NCAA and amateur referee for several decades.
