The Web Planet is a serial in the British science fiction television series Doctor Who, which was first broadcast in six weekly parts from February 13, 1965 to March 20, 1965.

The TARDIS is pulled off course by a mysterious force and trapped on the barren, desolate low-oxygen world of Vortis in the Isop galaxy. The Doctor, Barbara, Ian and Vicki are soon swept up in the struggles of the butterfly-like Menoptra, the original denizens of Vortis who were forced to flee the planet for the moon Pictos to escape the encroaching Animus and Zarbi. With assistance from the caterpillar-like Optera, the devolved descendants of the planet's original inhabitants, the TARDIS crew and the Menoptra are able to destroy the Animus at the center of its web complex.
