Cornelius "Don" Hiebert (August 2, 1862 – March 21, 1919) was a Russia-born Canadian politician from Alberta.

He was unable to obtain the Conservative nomination at the party's provincial convention in Red Deer that year.

Despite losing the Conservative nomination, Hiebert tried running in the provincial election to retain his seat in the new Didsbury electoral district.

He was defeated by Joseph Stauffer and ended up finishing the election in third place and losing his nomination deposit.

[5] After Hiebert was defeated from the Legislature, the Calgary Herald wrote in a scathing editorial that his wavering from Conservatism was spineless, and that even his adherent supporters now despise him.
