Crash Bash is a 2000 party video game developed by Eurocom Entertainment Software in association with Cerny Games and published by Sony Computer Entertainment for the PlayStation. It is the fifth title in the Crash Bandicoot series and the first entry in the series in the party genre. The game includes a collection of 28 mini-games playable within three modes of gameplay, as well as eight playable characters from the Crash Bandicoot series.

Crash Bash is the first game in the series not to be developed by Naughty Dog, as well as the last Crash Bandicoot game to be exclusively released on a Sony console, with subsequent installments being released on a wider variety of platforms. The game received mixed reviews from critics, who widely noted its similarity to Mario Party, but regarded it as an enjoyable multiplayer experience despite a perceived lack of depth and originality. The mini-games were determined to be varied but repetitive, and the graphics were appreciated for replicating the look and feel of previous Crash Bandicoot titles.
