The RPG-7 (Russian: РПГ-7) is a widely-produced, portable, unguided, shoulder-launched, anti-tank rocket-propelled grenade launcher. Originally the RPG-7 (Ручной Противотанковый Гранатомёт - Ruchnoy Protivotankovyy Granatomyot, Hand-held anti-tank grenade launcher) and its predecessor, the RPG-2, were designed by the Soviet Union and are now manufactured by the Bazalt company. The weapon has the GRAU index 6G3. The English-language term "RPG", meaning "rocket-propelled grenade", though frequently encountered and reasonably descriptive, is not based on a literal translation.

The ruggedness, simplicity, low cost, and effectiveness of the RPG-7 has made it the most widely used anti-tank weapon in the world. Currently around 40 countries use the weapon, and it is manufactured in a number of variants by nine countries. It is also popular with irregular and guerrilla forces. The RPG has been used in almost all conflicts across all continents since the mid-1960s from the Vietnam War to the present day War in Afghanistan.
