Mount Calvary Cemetery is located in north-central Davenport, Iowa, United States.

It was established as St. Marguerite's Cemetery in the 1850s on 20 acres (8.1 ha) of property donated by Antoine LeClaire.

Bishop Mathias Loras of Dubuque bought that property on January 17, 1849 from Judge G.C.R.

[3] The Mississippi and Missouri Railroad right of way was built through the southern section of the cemetery, and St. Mary's Church was erected on the property in 1867.

St. Mary's Cemetery was discontinued and the graves were moved to either Holy Family and Mount Calvary in the early 1900s.
