An object is to provide a novel heterocyclic compound which can be used for a light-emitting element, as a host material of a light-emitting layer in which a light-emitting substance is dispersed. Other objects are to provide a light-emitting element having low driving voltage, a light-emitting element having high current efficiency, and a light-emitting element having a long lifetime. Provided are a light-emitting element including a compound in which a dibenzo[f,h]quinoxaline ring and a hole-transport skeleton are bonded through an arylene group, and a light-emitting device, an electronic device, and a lighting device each using this light-emitting element. The heterocyclic compound represented by General Formula (G1) below is provided.
