We sequenced the complete chloroplast genome of Amorphophallus gigas, a perennial monocotyledonous herb in Araceae, using HiFi technology. The genome is 173,034 bp in length with a GC content of 34.96%. It exhibits a typical quadripartite structure: a large single-copy (LSC) region of 95,283 bp, a small single-copy (SSC) region of 15,675 bp, and a pair of inverted repeat (IR) regions of 31,038 bp each. It encodes 130 genes (85 protein-coding, 37 tRNA, 8 rRNA). Phylogenetic analysis revealed that A. gigas is closely related to A. titanum, forming a distinct clade. This study provides valuable genomic resources for understanding the evolution of Amorphophallus and Araceae.
