A dispersant for carbonaceous solid-water slurry which comprises a water-soluble copolymer of 1,000 to 600,000 in average molecular weight, obtained by polymerizing monomers comprised of (A) 0.1 to 7 mol % of polyalkylene glycol mono (meth)arcylate monomer, (B) 5 to 94.9 mol % of sulfoalkyl (meth)acrylate monomer, (C) 5 to 94.9 mol % of unsaturated carboxylic acid monomer, and 0 to 20 mol % of otner monomer (provided that the sum of these monomers is 100 mol %) and/or salt thereof. A carbonaceous solid-water slurry composition containing 0.01 to 5 parts by weight of the above dispersant per 100 parts by weight of the carbonaceous solid is also disclosed.
