Beam her up, Scotty.

Dorothy Catherine Fontana, a writer on the original “Star Trek” series credited with molding the character of Spock, has died at 80.

Fontana, the first female writer on the series, went by “D.C. Fontana” so producers in the 1960s wouldn’t know she was a woman.

She died Monday after a brief illness, the official “Star Trek” Web site reported.

“She was a pioneer. Her work will continue to influence for generations to come,” William Shatner, who played Captain Kirk, tweeted.

Fontana, a New Jersey native, also co-wrote the pilot for “Star Trek: The Next Generation” in 1987.
