Tokimeki Memorial 4 is a dating sim developed and published by Konami and the fourth game in the Tokimeki Memorial series. It is also the first original game in the series to debut on a portable system (the PSP). The game featured the return of the Tree of Legend from the first Tokimeki Memorial game, as well as the return of the Kirameki High school setting, set 15 years after the first game.

In Tokimeki Memorial 4, male players make their way through three years of high school, while trying to attract a female character from a pool of dateable characters. The game play focuses mainly on scheduling, dating, and stat-building. If the player is successful at wooing a female character by the end of the third year, then he will receive a confession of love at the Tree of Legend along with that character's special ending.
