Epinephrine (INN), also epinephrin (both pronounced ep-i-NEF-rin), or adrenaline (BAN) is a hormone and a neurotransmitter.

Epinephrine is sometimes shortened to epi in medical jargon.

Epinephrine plays a central role in the short-term stress reactions: the physiological response to threatening or exciting conditions (see fight-or-flight response).
