Provided are a carbon catalyst for hydrogen production having an excellent catalytic activity, a production method therefor, and a method of producing hydrogen using the catalyst. The carbon catalyst for hydrogen production is a carbon catalyst, which is obtained by carbonizing a raw material including an organic substance and a transition metal, the catalyst being used for hydrogen production by thermal decomposition of a hydrocarbon compound and/or an oxygen-containing organic compound. Further, the carbon catalyst for hydrogen production may be obtained by loading an alkaline earth metal on a carbonized material produced by the carbonization.
