We present a genome assembly from an individual female Accipiter gentilis (the northern goshawk; Chordata; Aves; Accipitriformes; Accipitridae). The genome sequence is 1,398 megabases in span. The majority of the assembly (99.98%) is scaffolded into 40 chromosomal pseudomolecules, with the W and Z chromosomes assembled. The complete mitochondrial genome was also assembled and is 16.6 kilobases in length.
