All-Star Thanksgiving Festival (Japanese: オールスター感謝祭), commonly referred to as All-Star Thanksgiving, is a Japanese television panel game and special program which has aired twice a year in April and October on TBS since October 1991.

In this article, the prototype Quiz! 25% Hit (Japanese: クイズ!当たって25%) is also explained.

The program features a large cast of celebrities such as actors, comedians and other tarento of around 160 to 200 people. The panel answers multiple quizzes every round until one person is deemed the winner either by elimination of those that answered incorrectly or by fastest response if there are multiple winners by the end of the round. During the program, numerous events and activities such as a mini-marathon are played by different contestants. It is a live broadcast which lasts about 5½ hours.

The winners of each quiz round and event earn a cash prize and the top overall performer at the end is considered the winner of the entire program.

This is one of the most known programs of Shinsuke Shimada and Wakako Shimazaki, especially of Wakako Shimazaki. In the program in which Wakako Shimazaki appeared, three programs All-Star Thanksgiving, Quiz! 25% Hit (its regular version) and Moero! Top Striker started in October 1991. All-Star Thanksgiving has become a masterpiece of Wakako Shimazaki, as well as Moero! Top Striker is the first anime of Wakako Shimazaki and a success story of Hikaru Kikkawa – a Japanese living abroad. The personalities of Wakako Shimazaki and Hikaru Kikkawa are incompatible, but both programs are similar in that they are "success stories".
