The "Dil Dhadakne Do" star's father died battling with cancer in 2013. A doctor by profession, he retired from the Indian Army in 1997 as Lieutenant Colonel.
"I miss my dad today. Always so happy for my achievements. The pride I saw in his eyes made me fly fearlessly knowing he'd catch me if I fall," Priyanka, who plays an FBI agent whose identity is shrouded by suspicion of being a terrorist in the show, tweeted on Tuesday.
The 33-year-old, who also has a tattoo of "Daddy's Li'l Girl" on her wrist, was crowned Miss World in 2000 and went on to join Bollywood in 2003 with "The Hero: Love Story of a Spy".
