Happy Software, Ltd. (Chinese: 吉喜軟体公司), also known as HappySoft, is a company located in Tokyo, Japan. The company is probably the only known unlicensed game company to deal with Super Famicom floppies. The company is known for making an unlicensed game for the Super Famicom in 1995 titled Hong Kong 97.

It is also known that the company has made a simulation game parodying the Japanese doomsday cult Aum Shinrikyo (otherwise known as Aleph) called The Story of Kamikuishiki Village for the NEC PC-98. The game have been incorrectly assumed by some as being created by, or in support of, the cult.
