We describe the complete mitochondrial genome sequence of Rasbora trilineata, which is a small cyprinid popular in aquarium trade. The circle genome (16,747 bp) has the typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding control region. The overall base composition of R. trilineata is 25.35% for T, 26.43% for C, 33.57% for A, and 14.65% for G, with a slight AT bias of 58.92%.
