Senjyo (センジョー) is an arcade game developed in 1983 by Tehkan (now known as Tecmo). The title of this game translates from Japanese as 'Battlefield'. The simple gameplay involves the player controlling a fixed turret on a tank shooting oncoming alien enemies through a cross-hair target. A certain number of enemies must be destroyed to progress to the next stage. The original arcade cabinet was a cocktail table.

The game was ported and published by Sony Corporation in 1984 for MSX computers.

In 2005, Senjyo was re-released exclusively on the Xbox, as part of the Tecmo Classic Arcade collection.
