Abstract: An organic compound that can provide a light-emitting device having a high hole-transport property and high reliability. An organic compound represented by General Formula (G1) shown below is provided. In General Formula (G1), X represents a sulfur atom or an oxygen atom, each of R1 to R22 independently represents any one of hydrogen, halogen, a nitrile group, an alkenyl group, a vinyl group, an alkynyl group, a straight-chain alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, an alkylsilyl group having 3 to 12 carbon atoms, an aryl group having 6 to 30 carbon atoms, and a heteroaryl group having 2 to 30 carbon atoms. At least one of R16 to R22 represents a naphthyl group, n represents an integer of 0 to 4, and Ar1 represents a fluorenyl group or a spirofluorenyl group.
