The Ralstonia solanacearum species complex (RSSC) is a globally distributed group of gram-negative, soil-borne bacteria that cause wilt disease on a broad range of host plant species. Tomato is a widely cultivated and economically important crop in Tanzania, but bacterial wilt disease caused by the RSSC has emerged to be one of the most devastating diseases in tomato producing regions in Tanzania. To investigate the genomic diversity of RSSC strains isolated from Tanzania, we generated draft genomes of 19 Ralstonia isolates from 5 villages in 4 regions. Our phylogenetic analysis showed that all 19 of the isolates were phylotype I R. pseudosolanacearum strains, of which 16 were sequevar 31, two were sequevar 48, and one was sequevar 46. Life IdentificationNumber (LIN) assignments were determined for all genomes. This genome announcement provides new genomic resources to investigate pathogen evolution, epidemiology, and virulence
