Dorothea Arnault (Japanese: ドロテア＝アールノルト, Hepburn: Dorotea Ārunoruto) is a character in the 2019 video game Fire Emblem: Three Houses.

She is a student of Garreg Mach University, belonging to the Black Eagles house, led by Edelgard von Hresvelg.

Dorothea is available to people who join the Black Eagles by default, though she can be recruited by members of competing houses Blue Lions and Golden Deer.

Dorothea also appears in Fire Emblem Warriors: Three Hopes, a game set two years after the beginning of Three Houses, premised on the idea that Byleth never became a Professor at Garreg Mach.

At one time, she was the most-used character in the game, Destructoid writer Chris Carter discussed that he used her often, calling her one of his favorite party members due in part to how enjoyable she was to talk to.

She appreciated how she stood up for herself against nobles who didn't have to work to get where they're at, or those who looked down on her,[11] The Gamer writer Stacey Henley discussed how Dorothea's design contrasted Bernadetta's in the pre-timeskip section of the game.

She discussed how, where Bernadetta is disheveled, Dorothea has to look her best due to her relative lack of money, as well as how her history with the opera house informs her outfit.

[12] Kotaku writer Maddy Myers identified the paralogue between Dorothea and Ingrid as one of her favorites, calling its story "surprisingly touching" and feeling that the two characters she became more attached to as a result.

[17] The Mary Sue writer Princess Weekes expressed surprise that the ship between Dorothea and Petra was not higher.
