The P-700 Granit (Russian: П-700 "Гранит"; English: granite) is a Soviet and Russian naval anti-ship cruise missile. Its GRAU designation is 3M45, its NATO reporting name SS-N-19 Shipwreck. It comes in surface-to-surface and submarine-launched variants, it can also be used against ground targets.

The P-700 was designed in the 1970s to replace the P-70 Ametist and P-120 Malakhit, both effective missiles but with too short a range in the face of improving weapons of U.S. Navy carrier battle groups. The missile was partially derived from the P-500 Bazalt.

Built by Chelomei/NPO Mashinostroenia, the bulging 10m missile has swept-back wings and tail, weighs around 7,000 kilograms and can be fitted with either a 750 kg HE warhead, a FAE warhead, or a 500 kt nuclear warhead. A stubby cylindrical solid-fuel rocket is fitted to the rear for launch; this booster stage is released when the missile enters sustained flight. For many years it was believed that this missile used a turbojet engine during the sustained flight; after the Russian and the Western media gained access to its performance characteristics, it was understood that its propulsion system was a ramjet. The P-700 has a distinctive annular air intake in the nose. Maximum speed is believed to be between Mach 1.6 and more than Mach 2.5. Range estimates vary between 400 km to 500 km to 550–625 km. The guidance system is mixed-mode, with inertial guidance, terminal active radar homing guidance and also anti-radar homing. Mid-course correction is probable.
