The 20-time grand slam champion cannot now be caught by US Open winner Daniil Medvedev and breaks the record he jointly held with Pete Sampras
Djokovic has topped the standings in seven of the past 11 seasons and broke the record for the most weeks at number one for any male player earlier this year.
He has now been number one for 345 weeks and counting, with his most recent spell beginning in February 2020.
Djokovic said: “(I’m) just proud and extremely happy. Obviously that was one of the biggest goals, and it’s always one of the biggest goals, to try to be number one and end the season as number one.
“To do it for the record seventh time and surpass my childhood idol and role model Pete is incredible. Very grateful, very blessed to be in this position.”
Djokovic returned to action this week for the first time since he fell one step short of a calendar Grand Slam by losing to Medvedev in the final in New York.
He has looked understandably a little rusty but recovered from a set down to defeat Hurkacz 3-6 6-0 7-6 (5).
The Pole had already achieved his main goal of the week by clinching the eighth spot at the ATP Finals later this month, and he hit back from 4-1 down in the deciding set to force a tie-break but fell just short.
