In 1859, the Cherokee Trail (and the Smoky Hill Trail -south branch) came down Cherry Creek Valley past the Four Mile House and through what is now called Glendale. The Four Mile House was one of the stage stops along the road, becoming a way station for freight wagons and a stock ranch.

The first documented use of the name Glendale was the Glendale Grange, which was organized in December 1896. J.M. and Agnes Riddle helped to found and donated land for a new Grange Hall that was completed in 1897. In 1902, William Harold Baumert named his dairy the Glendale Farm Dairy which solidified the term Glendale which is now used to describe the community.

In the 1920s, the property at the northeast corner of Virginia Avenue and Colorado Boulevard was purchased; in 1933, a retail beer license was applied for and granted.

A fossil was found in 1937 in the sands of the bed of Cherry Creek—the first evidence of prehistoric animals. Later that year, an upper molar of a mammoth was found and donated to Denver's Museum of Natural History.

The first Organizational Meeting of the Trustees of the Town of Glendale was held May 20, 1952, The citizens of the Glendale community wanted their voices to be heard fearing annexation from their large neighbor Denver and the loss of independence.  The original filing for incorporation of the Town of Glendale was incorporated January 8, 1952.
