No, your best bet for a hamster is going to be a leash made for a reptile--like a small iguana or monitor. Still, even if it would fit, I would imagine it would be very tough to get the hamster to sit still long enough to put the harness on, and even harder to get it to stay on. Leashes aren't a great option for animals that small, as they'll generally be inefficient, impractical, or unsafe. Playpens and shirt pockets are the way to go :)
