The alpha-2B adrenergic receptor (α_2B adrenoceptor), is a G-protein coupled receptor. It is a subtype of the adrenergic receptor family. The human gene encoding this receptor has the symbol ADRA2B. ADRA2B orthologs have been identified in several mammals.

α₂-adrenergic receptors include 3 highly homologous subtypes: α_2A, α_2B, and α_2C. These receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system.
