Alphys (/ˈælfiz, ˈælfɪs/) is a character in the 2015 video game Undertale and the 2018 video game Deltarune. She is a bisexual reptilian monster who serves as a scientist under the leader of the Underground, Asgore, and is a fan of anime and manga. She is also a friend to Mettaton, a robot, and the captain of the Royal Guard, Undyne, who eventually becomes her girlfriend. She suffers from social anxiety, depression, and self-harm tendencies, and the depiction of her struggles with these have been the subject of praise and commentary by critics. She watches the player-character throughout the game, offering guidance at some point, though with limited benefit. She is revealed to have dark secrets, including ones that relate to experimentation. She also appears in Deltarune in a different role as a school teacher.

Alphys was designed by Toby Fox and Temmie Chang. She was initially conceived as a male character, but Fox did not like this, so he made minor changes to her design and changed her gender. She has received generally positive reception, though some critics identified her as an annoying character. She has been identified as a positive representation of both mental illnesses and LGBTQ+ characters, with multiple critics identifying her as a relatable character. Alphys overcoming her issues was particularly cited as a strong example of Undertale's message of characters finding courage in themselves by Destructoid writer CJ Andriessen.
