5-Hydroxytryptamine receptor 2B (5-HT_2B) also known as serotonin receptor 2B is a protein that in humans is encoded by the HTR2B gene. 5-HT_2B is a member of the 5-HT₂ receptor family that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT).

The 5-HT₂ receptors (of which the 5-HT_2B receptor is a subtype) mediate many of the central and peripheral physiologic functions of serotonin. Cardiovascular effects include contraction of blood vessels and shape changes in platelets; central nervous system effects include neuronal sensitization to tactile stimuli and mediation of some of the effects of hallucinogenic substituted amphetamines.
