This is a non-exhaustive list of playable characters in Honkai: Star Rail.

For a lot of the earlier characters, their information in 'Character Introduction' slightly differs from their 'Character Details' (some being very different, while others are rephrased versions). In later character bios, these have a tendency to be identical. If it's missing, it's because it was the exact same.
