A novel organic compound is provided. That is, a novel organic compound that is effective in improving the element characteristics and reliability is provided. An organic compound has a benzonaphthofuran skeleton and a triazine skeleton and is represented by General Formula (G1) below. (In the formula, Ar1, Ar2, and Ar3 separately represent a substituted or unsubstituted phenylene group, and each of m and n is independently 0 or 1. R1 and R2 separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted methylfluorenyl group, a substituted or unsubstituted dimethylfluorenyl group, a substituted or unsubstituted spirofluorenyl group, a substituted or unsubstituted naphthyl group, or a substituted or unsubstituted phenanthrenyl group. B1 to B3 separately represent nitrogen or carbon, and at least one of B1 to B3 represents nitrogen. In addition, A is represented by General Formula (G1-1). Any one of R3 to R12 is bonded to Ar1, and the others separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted methylfluorenyl group, a substituted or unsubstituted dimethylfluorenyl group, a substituted or unsubstituted spirofluorenyl group, a substituted or unsubstituted naphthyl group, or a substituted or unsubstituted phenanthrenyl group. Furthermore, Q represents S or O.)
