Signaling peptide receptor is a type of receptor which binds one or more signaling peptides or signaling proteins.

An example is the tropomyosin receptor kinase B (TrkB), which is bound and activated by the neurotrophic protein brain-derived neurotrophic factor (BDNF). Another example is the μ-opioid receptor (MOR), which is bound and activated by the opioid peptide hormone β-endorphin.
