Horace William Shaler Cleveland was an American landscape architect. His approach to natural landscape design can be seen in projects such as the Grand Rounds in Minneapolis; Sleepy Hollow Cemetery in Concord, Massachusetts; the boulevard system in Omaha, Nebraska; Roger Williams Park in Providence, Rhode Island; and St. Anthony Park in Saint Paul, Minnesota.

Boulevards in Omaha are part of a park and boulevard system originally designed in 1889 by Horace Cleveland. There are more than one hundred miles (160 km) of boulevards throughout the city of Omaha, Nebraska today.
