The Hopman Cup XXIX (also known as the 2017 Mastercard Hopman Cup for sponsorship reasons) was the 29th edition of the Hopman Cup tournament between nations in men's and women's tennis. It took place at the Perth Arena in Perth, Australia.
The defending champions were Australia. Roger Federer, 2001 champion, made his first appearance since 2002, alongside his partner Belinda Bencic.
For this edition, the Fast4 rule was implemented in Mixed Doubles matches. This marked the first time that an official tournament applied this rule since its inception in 2015.
On 4 January 2017, a Perth Arena record crowd of 13,785 attended the tournament for the match between Germany and Switzerland. This was also the highest attendance for a tennis match in Western Australian history.
In the final France defeated the USA to win its second title.
