Psyvariar (サイヴァリア, Saivaria) is a vertically scrolling shooter arcade game series developed by Success Corporation on Taito's G-NET hardware.

City Connection developed a port to consoles and PC titled Psyvariar Delta.

A further enhanced arcade version titled Psyvariar Delta AC was developed by City Connection and released on exA-Arcadia in December 2020.

More difficult (and higher-scoring) areas become selectable only if the fighter's level reaches the requirement before choosing next stage.

Unlike Normal mode, if player loses all lives in a stage, the game cannot be continued.

If a sufficiently high fighter level is not achieved the game will end after stage X-B.

The Special Sound Box included an audio CD of the game's soundtrack, and the Special Capture Box included a gameplay DVD of both games being fully completed by expert players.

The PlayStation 2 versions of the individual games were later released separately as budget range titles.

The European version retained all the features of the Japanese release and includes a 60 Hz mode.
