Juliana Renée Thiessen Day (born 1980 in Regina, Saskatchewan, Canada) is a former Miss Canadian Universe and the Canadian representative to the Miss Universe pageant in 1998.
She married Logan Day, son of former Canadian Alliance leader Stockwell Day, in 1999.
In 2000, Thiessen Day was briefly the source of a minor scandal in Canada. During the CBC television coverage of the federal election, live footage of Thiessen Day at Alliance campaign headquarters was shown.

Because the Canadian television networks were using a shared video and audio feed, his comments were broadcast on CTV and Global stations as well. The producer was forced to apologize.
