4) Nepal (Population - 29,391,883)

Nepal has the dubious designation as the most populous nation to compete in both the winter and summer games and still be medal-less. Many Nepalese would probably be quick to point out that they do have one bronze medal. Unfortunately it came in taekwondo at the Seoul Olympics, when that sport was still only in exhibition.

Best Shot At A Medal: Prasiddha Jung Shah is a promising swimming talent despite a strong field of competition in the Men's 50m Freestyle.
