Has supergirl been in the dceu?

Supergirl made her on‑screen debut in the 2023 DC Extended Universe film The Flash. In that movie, she is portrayed by Sasha Calle and appears briefly as a superheroine who has recently arrived on Earth. The film is one of the official entries in the DCEU, which includes titles such as Batman v Superman: Dawn of Justice and Aquaman. The 2026 standalone Supergirl film, directed by Craig Gillespie, is slated for the newer DC Universe (DCU) and is separate from the DCEU timeline. Therefore, Supergirl has indeed appeared in the DCEU, but only in the 2023 The Flash film.
