Masanori "Mashi" Murakami (村上 雅則, Murakami Masanori, born May 6, 1944) is a retired Japanese baseball player. He is notable for being the first Japanese player to play for a Major League Baseball team. Sent over to the United States by the Nankai Hawks, Murakami saw success as a reliever for the San Francisco Giants, debuting at the age of 20 in .
