In this article, we report draft genome sequence and annotation of Klebsiella quasipneumoniae from the wastewater source in Bangladesh. Here, we identified Klebsiella quasipneumoniae strain C11S11_BCSIR, a multidrug-resistant pathogenic bacterium harboring seven antimicrobial resistance genes of five major antibiotic classes with a novel multilocus sequence type (MLST) (ST6130).
