Wall Street Kid is a video game for the Nintendo Entertainment System in which the main character, in order to gain a six-hundred-billion-dollar inheritance from a distant relative, must prove himself worthy by taking $500,000 in seed money and successfully investing it in the U.S. stock market.

Wall Street Kid is indirectly based on a series of Japanese Famicom games. These games were individually titles as Money Game and The Money Game II: Kabutochou no Kiseki. In both games, the same goal to acquire as much money as possible remains. However, Wall Street Kid uses American dollars while Money Game uses Japanese yen.
