Dragon Quest XI: Echoes of an Elusive Age is a role-playing video game developed and published by Square Enix. An enhanced version, Dragon Quest XI S: Echoes of an Elusive Age - Definitive Edition, was released in September 2019 for the Nintendo Switch.

One of the first games announced for the Nintendo Switch video game console, the game was originally conceived as an open world game, but the idea was discarded when it conflicted with the story the developers wanted to tell. To increase the awareness of the Dragon Quest franchise in the west, support for Microsoft Windows and features such as voiced English dialogue and support for 4K resolution were included. Elements added later included an expanded plot and an option to listen to an orchestral version of the score.
