The following image shows roughly how the genes are laid out in HIV (remember that HIV-1 and HIV-2 are quite different). Click on a gene's name for more information.
This diagram is based on a fantastic map of the HIV-1, HIV-2, and SIV genomes, available at
The genes in HIV's genome are as follows:
The HIV genome also has a "Long Terminal Repeat" (LTR) at each end of its genome - not quite a gene, but a sequence of RNA/DNA which is the same at either end and which serves some structural and regulatory purposes.
