"Happy Thanksgiving from us to you!" the Oscar winner captioned the pic, which shows her and the Coldplay singer on opposite ends of the group shot, while their children Apple, 11, and Moses, 9, stood in the center of the pic.
Paltrow, 43, announced their separation in a statement on her Goop website in March 2014, explaining their decision to "consciously uncouple."
She wrote that the pair, who'd been married for 10 years, "always will be a family, and in many ways we are closer than we have ever been."
They have remained amicable since then, and in September this year, Paltrow shared a snapshot of their children watching Martin (who she referred to as "baby daddy") performing with Ed Sheeran.
The exes, whose divorce was reportedly finalized this past April, have also moved on. Us Weekly exclusively confirmed in August 2014 that Paltrow is dating Glee co-creator Brad Falchuk, while Martin, 38, had an on-off relationship with Jennifer Lawrence for almost a year before moving on to Peaky Blinders actress Annabelle Wallis.
