Sriharikota (Telugu: [ʃriːhɐɾikoːʈɐ]) is a barrier island off the Bay of Bengal coast located in the Shar Project settlement of Tirupati district in Andhra Pradesh, India.

It houses the Satish Dhawan Space Centre, one of the two satellite launch centres in India (the other being Thumba Equatorial Rocket Launching Station, Thiruvananthapuram).

Sriharikota was selected by ISRO because of its proximity to the equator, it gives extra centripetal force from the rotation of Earth.

The island separates Pulicat Lake from the Bay of Bengal.

A 16 km elevated road connects Sriharikota to the mainland.
