Electro is either (a) a prefix used to indicate a relationship to electricity, as in electro-mechanical, or electro-magnet, or (b) a stand-alone word.

When used alone, it can refer to:

• The music genre of electro, a more electronic, robotic variant of hip hop music
• Genres descended from electro, such as electroclash or electropop, although this use is considered erroneous
• The various fictional Marvel Comics comic-book villains named Electro
• The robot Electro from Marvel Comics' 1940s predecessor, Timely Comics
• A type of copy of an object made using electrolysis (short for "electrotype")
• A series of cameras made by Yashica (Electro 35, TL Electro)
