Alan Wayne Allard (born December 2, 1943) is a member of the Republican Party, and was a United States Senator from Colorado. He did not seek re-election in 2008.

Allard was born in Fort Collins, Colorado to Sibyl Jean Stewart and Amos Wilson Allard. He was raised on a ranch near Walden, Colorado. He received a Doctor of Veterinary Medicine degree from Colorado State University in 1968.

Allard continued to run a veterinary practice full-time, while representing Larimer and Weld Counties in the Colorado State Senate, from 1983 to 1990. During his tenure he was a strong supporter of fiscal responsibility and the preservation of a citizen legislature. Allard's influence on local politics is still felt today as he is the sponsor of Colorado's law limiting state legislative sessions to 120 days.
