Toprak, who penned additional music for the DC film "Justice League", is the first female composer to score a major comic-book movie, reports variety.com.
"Captain Marvel" also happens to be about a female superhero (played by Brie Larson).
Toprak said in a social media post: "It's an incredible honour to be a part of the Marvel Universe… I have so many people to thank for helping me on this journey but first and foremost, my incredible agents Laura Engel and Richard Kraft for believing in me from day one."
She also thanked directors Anna Boden and Ryan Fleck "for giving me this opportunity of a lifetime" and Marvel music supervisor Dave Jordan.
