Suzanne Elizabeth Ungerleider, who formerly wrote and performed under the name Oh Susanna, is an American-Canadian alternative country singer-songwriter from Vancouver, British Columbia.

Ungerleider chose to perform under the name Oh Susanna, alluding to the classic American folk song "Oh! Susanna", rather than her given name as a means of keeping her private and professional lives separate. She initially wanted to be a somewhat theatrical performer. "I had this notion, okay I'm going to try and wear these vintage clothes and I play this old Stella guitar, which is like this mail order guitar that blues guys used to play," said Ungerleider.
