A novel organic compound that can be used as an electron-injection material or an electron-transport material of a light-emitting element is provided. An organic compound with which a display device having less crosstalk can be obtained is provided. A light-emitting device, a display device, and an electronic device each having less crosstalk are provided. An organic compound including two or three benzo[h]quinazoline rings is provided. In the organic compound, two or three benzo[h]quinazoline rings are preferably included in the substituent including an aromatic ring or a heteroaromatic ring and having 3 to 30 carbon atoms. When two or three benzo[h]quinazoline rings are included in a substituent particularly including a heteroaromatic ring and having 3 to 30 carbon atoms, a high electron-transport property can be obtained.
