Akihiko Tago (多胡 昭彦 Tago Akihiko?) is a Japanese astronomer.

He co-discovered several comets, including C/1968 H1 (Tago-Honda-Yamamoto), C/1969 T1 (Tago-Sato-Kosaka), C/1987 B1 (Nishikawa-Takamizawa-Tago).

He also discovered several novas, including V1493 Aql (Nova Aquilae 1999), V2275 Cyg (Nova Cygni 2001 no. 2), V574 Pup (Nova Puppis 2004) and V2467 Cyg (Nova Cygni 2007).

In 2006 he was the first astronomer to discover a micro-lensing system outside the Magellanic Clouds and the bulge of our Milkyway. The star GSC 3656-1328 suddenly brightened by four magnitudes in two weeks time and returned to its normal brightness two weeks later. A red or a brown dwarf star passed exactly in front of GSC 3656-1328 and the gravity of the dwarf star directed more light to the observers on Earth.
