Kartik Tiwari (born 22 November 1990), known professionally as Kartik Aaryan, is an Indian actor who appears in Hindi films. While pursuing an engineering degree in biotechnology, he dabbled in modelling and made attempts to start a career in film. After struggling for three years, Aaryan made his acting debut in 2011 with Pyaar Ka Punchnama, a buddy film about the romantic tribulations faced by three young men, which was directed by Luv Ranjan and co-starred Nushrat Bharucha.
Aaryan went on to play the romantic interest of the lead female characters in Akaash Vani (2013) and Kaanchi: The Unbreakable (2014), but these films failed to propel his career forward. He subsequently collaborated with Ranjan and Bharucha in two more buddy films, Pyaar Ka Punchnama 2 (2015) and Sonu Ke Titu Ki Sweety (2018), both of which were commercially successful but received criticism for their misogynistic themes. The latter proved to be a breakthrough for Aaryan, and he followed it by starring in the 2019 romantic comedies Luka Chuppi and Pati Patni Aur Woh.
In addition to his acting career, Aaryan endorses several brands and products, and has co-hosted two award ceremonies. He appeared in Forbes India's Celebrity 100 list of 2019.
He is also known as Kartk Tiwari.
