Oakdale Memorial Gardens, formerly Oakdale Cemetery, is located in east-central Davenport, Iowa. It contains a section for the burial of pets called the Love of Animals Petland. In 2015, the cemetery was listed as an historic district on the National Register of Historic Places, and as a local landmark on the Davenport Register of Historic Properties. It is also listed on the Network to Freedom, a National Park Service registry for sites associated with the Underground Railroad.

Oakdale was established as a non-profit cemetery by a group of Davenport businessmen as an alternative to the overcrowded Davenport City Cemetery and the for-profit Pine Hill Cemetery. It was incorporated as the Oakdale Cemetery Company May 14, 1856. The cemetery board hired Captain George F. de la Roche, who had finished the design of Oak Hill Cemetery in Washington, D.C. five years earlier, to complete the design and platting of the cemetery. It was designed as a rural or garden cemetery, but it transitioned to a landscape-lawn cemetery beginning in the late 19th century. It covers more than 78 acres (32 ha). The first numbered burial at Oakdale was that of three-month-old Mary Larned Allen on September 15, 1857, though several earlier burials were recorded at a later date, some from as early as October, 1855. Some of the graves in the cemetery had been transferred from the overcrowded City Cemetery in the west end. The cemetery is located across Eastern Avenue from the former Iowa Soldiers' Orphans' Home, and it contains the graves of the orphans that died at the home. There are also at least 11 graves of former slaves who escaped to freedom by way of the Underground Railroad, which led to its inclusion on the Network to Freedom.

Two special receiving vaults were built in the cemetery, although neither exists anymore. A brick vault was constructed in 1873 for those who died in the winter when the ground was frozen. A wooden vault was built next to it in 1918 because of the large number of deaths as a result of the Spanish flu epidemic.

The cemetery entrance is marked by a set of monumental gates, designed in the Art Nouveau style by Davenport architect Edward Hammatt in 1895. Construction of the gates was completed in 1896.

The cemetery is also home to several private mausoleums. William D. Petersen was the son of J.H.C. Petersen who founded a department store in Davenport that has become Von Maur. He also was responsible for the development of the city's riverfront and built the LeClaire Park Bandshell there. His mausoleum was designed in the Gothic Revival style by Davenport architects Rudolph Clausen & Walter Kruse. It was inspired by his wife Sara's desire for a tomb similar to the ones she saw in Europe. It was constructed by Presbrey Leland of Valhalla, New York in 1921 for $60,000. The exterior is composed of limestone from Greece. The interior features crypts that were carved from Greek marble and a ceramic tile ceiling that was designed and completed by the Guastavino Tile Company of Woburn, Massachusetts.

Joseph W. Bettendorf was an industrialist for whom the city of Bettendorf, Iowa is named. His mausoleum was built in 1923 in the Egyptian Revival style for $150,000. Its exterior is composed of Barre Granite from Vermont. The interior features crypts carved from white marble and Egyptian-inspired stained glass windows.

The mausoleum built for Johanna Schricker, widow of Davenport lumber magnate Lorenzo Schricker, was designed in the Neoclassical style by Davenport architect John W. Ross. It was built by the Vermont Marble Company in 1899 at a cost of $6,489. The inspiration for the structure was the North Portico of the White House in Washington, D.C. Its exterior is composed of Sutherland Falls white marble and features a bronze roof supplied by the Winslow Brothers of Chicago.

There is a Soldiers' Lot near the center of the cemetery, which is administered by the U.S. Department of Veterans Affairs. At one time 174 soldiers were buried at Oakdale, including the first Iowans to die in the Civil War at the Battle of Fort Donelson. Most of the bodies were transferred in 1888 to Rock Island National Cemetery or Keokuk National Cemetery. The remaining 14 soldiers' graves were moved to the Grand Army of the Republic (GAR) plot in 1900. The plot was transferred from the GAR to the cemetery association in 1940 and the United States government took possession of it the following year. Today it contains the remains of 71 soldiers from the Civil War and Spanish–American War.
