The invention discloses a crynebacterium glutamicum engineering strain for producing 5-aminolevulinic acid and a construction method thereof. The construction method comprises the steps of 1, knocking out lactic dehydrogenase encoding gene idhA, and acetic acid generation genes pta-ackA, pqo and cat in the corynebacterium glutamicum, inserting a strong sod promoter in front of a phosphoenolpyruvate carboxylase encoding gene ppc, knocking out a phosphoenolpyruvate carboxykinase pck, thus acquiring the strain CB6; 2, knocking out a penicillin-binding protein encoding gene pbpla in the strain CB6, thus acquiring the strain CB7; transferring the plasmid pXA of a built over-expressed 5-aminolevulinic acid synthase gene into the strain CB7, thus acquiring the engineering strain L2. According to the engineering strain provided by the invention, the 5-aminolevulinic acid is produced in a medium in which 10g/L glucose is added as a carbon source; compared with reference strains, the engineering strain is respectively improved by 13.53% and above.
