Lorvan crackers are a snack food, a variety of cracker served at Quark's on Deep Space 9.

When Doctor Julian Bashir diagnosed Major Kira Nerys with being overworked and suffering from extreme stress and borderline exhaustion, he offered her Karvino juice, Lorvan crackers, a holosuite program, a Jumja stick and gambling tokens. Kira was told she had to enjoy two of the offers before she was allowed to leave Quark's establishment. (DS9: "Defiant")
