Flower-like　MoS2　supported　on　three-dimensional　graphene　aerogel　(MoS2/GA)　composite　has　been　prepared　by　a　facile　hydrothermal　method　followed　by　subsequent　heat-treatment　process.　Each　of　MoS2　microflowers　is　surrounded　by　the　three-dimensional　graphene　nanosheets.　The　MoS2/GA　composite　is　applied　as　an　anode　material　of　sodium-ion　batteries　(SIBs)　and　it　exhibits　high　initial　discharge/charge　capacities　of　562.7　and　460mAhg(-1)　at　a　current　density　of　0.1Ag(-1)　and　good　cycling　performance　(348.6mAhg(-1)　after　30　cycles　at　0.1Ag(-1)).　The　good　Na+　storage　properties　of　the　MoS2/GA　composite　could　be　attributed　to　the　unique　structure　which　flower-like　MoS2　are　homogeneously　and　tightly　decorated　on　the　surface　of　three-dimensional　graphene　aerogel.　Our　results　demonstrate　that　as-prepared　MoS2/GA　composite　has　a　great　potential　prospect　as　anodes　for　SIBs.
