To provide an improved steam reforming catalyst for lower hydrocarbons which is highly active and has a high crushing strength. An improved steam reforming catalyst for lower hydrocarbons comprising a support constituted of CaO and Al.sub.2 O.sub.3 and an active component comprising nickel or a platinum-group metal. The content of CaO is 0.5 to 25 wt% based on the catalyst, and at least part of the CaO forms compounds with the A1.sub.2 O.sub.3. The support has a void fraction X of pores with a diameter of 0.5 .mu.m to 20 .mu.m of 0.08 or higher, a void fraction Y of pores with a diameter smaller than 0.5 .mu.m of 0.15 or higher, and a total void fraction Z of 0.23 to 0.8 (provided that Z.ltoreq.(X+Y)).
