The Gakken Compact Vision TV Boy (Japanese: TV ボーイ, Hepburn: TV bōi) is a second generation home video game console developed by Gakken and released in Japan in 1983 for a price of ¥8,800.

The system was made to compete with the Epoch Cassette Vision, which had a market dominance of 70% in Japan.

The console was released months after the Nintendo Famicom and Sega SG-1000 which, although more expensive at ¥15,000, were more advanced and had more features as well as bigger games libraries; furthermore, Epoch had just launched the Cassette Vision Jr. revision for ¥5,000. These factors made the system obsolete from the start, with a high price tag, very few and comparably rudimentary games, and a strange form factor, leading to poor sales. As a result, it is now a very rare collector's item among some retro gamers.
