Milwaukee Country Day School (MCD) was a country day school in Whitefish Bay, Wisconsin. It operated under the headmastership of A. Gledden Santer. The school was begun in 1917, "incorporated by leading citizens.". According to alumnus Henry Reuss, "Country Day, with its Church of England prayers, its 'body sports' and its Latin studies, marked the general de-Germanization of Milwaukee culture which occurred in the 1920s." The school appears in the novel Shadowland by alumnus Peter Straub.
