The VCS 3 (or VCS3; an initialism for Voltage Controlled Studio, version #3) is a portable analog synthesizer with a flexible modular voice architecture introduced by Electronic Music Studios (EMS) in 1969.[# 1]

EMS released the product under various names. Logos printed at the console's front left (see photos) say "V.C.S. 3" on the most widely sold version; "The Putney (VCS 3)" on the earlier version; and "The Synthi (VCS 3) II" on the later version (Synthi VCS 3 II).[# 2]
