Provided are a thermal siphon reactor and a hydrogen generator including the same. The hydrogen generator including the thermal siphon reactor includes: a housing; a reaction source container disposed in the housing; a reactor tube connected to the reaction source container in which a catalytic reaction of a reaction source provided from the reaction source container occurs; a catalyst layer which is porous, facilitates gas generation by being contacted with the reaction source, and is disposed in the reactor tube; and a product container which is connected to the reactor tube and collects a reaction product generated in the reactor tube, wherein in the reactor tube, a convection channel through which the reaction product is discharged passes through the reactor tube in the lengthwise direction of the reactor tube. The thermal siphon reactor and the hydrogen generator including the same have a self-operating ability, operate at low costs, and have small installment volume.
