Murray said: "It's great to have qualified again for London. I've played some of my best tennis this year on home soil, so hopefully I can also have a good run at The O2 in November. The atmosphere and the support I've had there has always been incredible."
The 25-year-old has already won gold in the Olympics this summer in London and will be hoping for more success in the British capital in November.
Four other players will take part in the tournament at The O2.
