Best Guy (ベストガイ, Besuto Gai) is a 1990 Japanese action film directed by Tōru Murakawa, and produced by Toei Company in association with Mitsui & Co. and Tohokushinsha Film. The screenplay was written by Murakawa with Makoto Takada. The film stars Yūji Oda, Naomi Zaizen, Masato Furuoya, Masato Nagamori, and Toshio Kurosawa. The title refers to the highest rank of the JASDF's F-15J training program.

The film's aerial scenes were produced in cooperation with the JASDF, using the Mitsubishi F-15J - the country's variant of the McDonnell Douglas F-15 Eagle. Seen by movie critics as a copy of Top Gun, Best Guy was a box-office failure in Japan, earning ¥230 million.
