Naveen Kumar Gowda (born 8 January 1986), known professionally as Yash, is an Indian actor who predominantly works in Kannada cinema. One of the highest paid and leading actors in Indian cinema, Yash is a recipient of several accolades including three Filmfare Awards South and five SIIMA Awards.

Yash began his career with appearances in several television series in the 2000s. He made his film debut in 2007 with Jambada Hudugi. The 2008 romantic drama Moggina Manasu, for which he received the Filmfare Award for Best Supporting Actor, proved to be a breakthrough role for Yash.

His first film in a leading role, Rocky (2008), was poorly received by critics and a box office flop. Yash went on to establish himself as a leading actor of Kannada cinema with the college romance Googly (2013), comedy-drama Raja Huli (2013), fantasy action Gajakesari (2014), romantic comedy Mr. and Mrs. Ramachari (2014), action comedy film Masterpiece (2015) and action romance Santhu Straight Forward (2016), all of which became commercial successes. The pan-India success of Prashanth Neel's KGF franchises which consists of KGF: Chapter 1 (2018) and KGF: Chapter 2 (2022), helped Yash attain nationwide recognition. The former earned him the Filmfare Award for Best Actor – Kannada and the latter ranks as the highest-grossing Kannada film.

Yash is a philanthropist and promotes social causes through the Yasho Marga Foundation, a charitable foundation established by him and his wife. Yash is married to actress Radhika Pandit, with whom he has two children.

Yash was born on 8 January 1986 in Boovanahalli, a village in Hassan, Karnataka. He was given two names: Naveen legally, and his mother's side of the family named him Yashwanth. Yashwanth was chosen as they believed his time of birth astrologically necessitated a name beginning with the letter ಯ (ya). In keeping with a Hindu tradition of giving children a deity's epithet, Yash was described as Nanjundeshwara ("poison-drinker god", referring to Shiva). Before starting his acting career, he was advised by others in the industry to adopt a stage name. Desiring to stand out with a name that was unique, he shortened Yashwanth to Yash.

Yash's father, Arun Kumar, was a driver for the Karnataka State Road Transport Corporation and later the Bangalore Metropolitan Transport Corporation. His mother, Pushpa, is a homemaker. He has a younger sister, Nandini, who is married to a computer engineer. Yash aspired to be an actor from a young age and actively participated in theatre and dance competitions at his school in Mysore. When he was young, his family also ran a provision store, where he would help out regularly. Yash wanted to quit school and pursue full-time acting after completing grade 10 but had to complete senior school on the demand of his parents. He studied at the Mahajana Education Society for all his school years. His parents initially disapproved of his acting ambitions, and his father wanted him to be a government officer. In 2003, they relented and allowed him to move to Bangalore at the age of 16 to work on a film as an assistant director, but stated that he would not be allowed to go back if he returned. The project was cancelled after only two days of filming, but Yash stayed in Bangalore. He stated he had ₹300 (equivalent to ₹1,100 or US$13 in 2023) with him at the time. He joined a theatre group, the Benaka drama troupe, which was formed by dramatist B. V. Karanth. He worked as a backstage worker and was paid ₹50 (59¢ US) per day.

Yash eventually became a backup actor, and in 2004, portrayed Balarama, the lead role in a play. While still working in theatre, he completed his Bachelor of Arts at Bangalore's K.L.E. College. He made his television debut the same year with the teleserial Uttarayana. In 2005, he was offered a role in the teleserial Nanda Gokula, where he starred alongside Radhika Pandit. He went on to appear in several other teleserials such as T. N. Seetharam's Male Billu and Preeti Illada Mele. Once Yash had secured a stable income, his parents moved in with him to Bangalore. During this time, he was offered roles in seven films, but his insistence on having the script for each film made available to him was viewed as "arrogance from a newcomer" and often refused.

Yash debuted in 2007 with a supporting role in Priya Hassan's Jambada Hudugi, which saw him play a man whose infertile wife seeks uterus transplantation. A critic from Indiaglitz wrote that "Yash is very good in his debut". He next played the romantic interest of his Nanda Gokula co-actor Radhika Pandit's character in the teen drama Moggina Manasu (2008), directed by Shashank, which follows the love lives of four girls who become friends in college. He was cast in a last-minute decision after Shashank's initial choice for the role fractured their leg and required rest for six months. Shashank then happened to see Yash in an episode of Preeti Illada Mele and was impressed by his performance. Yash was sporting a beard for Preeti Illada Mele but Shashank reached out to him and convinced him to shave clean for the role. R.G. Vijayasarathy of Rediff.com found the film worked despite its screenplay and highlighted Yash's performance among the male cast as impressive. The role won him the Filmfare Award for Best Supporting Actor in Kannada at the 56th Filmfare Awards South. The film is considered to be Yash's breakthrough project.
