"Visiting pops with mama g," Hudgens, 27, captioned a pic of the moment she shared on Instagram.
In the snap, the Grease: Live! star and her mother smile as they sit on the grass near the grave.
The actress lost her father, Greg, in late January, just hours before she performed in the live musical on FOX.
"I am so sad to say that last night my daddy, Greg passed away from stage 4 cancer," she tweeted. "Thank you to everyone who kept him in your prayers. Tonight, I do the show in his honor."
While accepting her award for Breakthrough Performer at the 2015 Industry Dance Awards in August, Hudgens revealed that her father had been diagnosed with cancer.
"Last year, my boyfriend, Austin, lost his mom, Lori, to cancer, and my dad has just been recently diagnosed with stage four cancer," Hudgens said at the event. "Let me tell you, I hate cancer. I hate cancer with every cell of my being."
