Moroccan born 26-year-old Imane Boudlal, who was working as a hostess at Storyteller's Café in Disney's Grand Californian Hotel, said that she wore the hijab for Ramadan, and her employers told her that she would have to work in the back of the restaurant and not serve customers, The Sun reported.
Her supervisors allegedly told her it was not the "Disney look".
The complaint has been filed with the US Equal Employment Opportunity Commission.
Disney, however, asserts that it did not discriminate against Boudlal and had offered to make a hijab to their design, The Sun said.
But Bouldal insists that she was wearing her own headscarf because Disney did not give her one.
Disney spokeswoman Suzi Brown said the hijab would be a departure from the costume policy for Boudlal's role as hostess at the restaurant.
"It has to do with the costume, every role at Disneyland Resort has a specific costume," she said.
Bouldal's lawyers said she only realised she could wear a hijab while taking her US citizenship exam.
