A beautiful college student from Long Island has been missing in Hawaii for more than a week, cops said last night.

Chelsea Ryan, 21, originally from Huntington, was last seen by her roommates at the University of Hawaii on April 28.

Hawaiian cops said they did not immediately suspect foul play.

But her worried family said she’s never gone this long without calling — and that they haven’t any idea where she could be.

“She’s a straight-A student, she’s a good girl,” her aunt Joani Bosco told The Post.

Bosco added that calls to her niece’s cellphone go directly to voicemail.

“She’s a vibrant young woman. We need her to be found, we need her to be safe. The family is desperate to know where she is.”
