Aleksandr Davidovich Nadiradze (Georgian: ალექსანდრე ნადირაძე, Russian: Александр Давидович Надирадзе 20 August 1914 – 3 September 1987) was a Soviet engineer of Georgian ethnicity who was instrumental in former Soviet Union's aerospace and defense technology. He developed various missiles, bombs, shells and is considered "father" of the mobile ICBMs, having created the RT-21 Temp 2S (SS-16), RSD-10 Pioneer (SS-20) and the RT-2PM Topol (SS-25). More modern weapons such as the RT-2PM2 Topol-M and RS-24 are mostly based on Nadiradze's work as well.
