Objects are to provide the following: a substance that facilitates hole injection and has high triplet excitation energy; a light-emitting element having high emission efficiency using the substance that facilitates hole injection and has high triplet excitation energy; a light-emitting element having low driving voltage; and a light-emitting device, an electronic device, and a lighting device having low power consumption. Provided is a triazole derivative in which a dibenzothiophen-4-yl or dibenzofuran-4-yl group represented by General Formula (G2) is bonded to any one of Ar1 to Ar3 of a triazole derivative represented by General Formula (G1). In the formulas, A represents oxygen or sulfur, Ar1 to Ar3 separately represent a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and R1 to R7 separately represent hydrogen, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.
