Pundalik (Marathi: पुंडलिक) or Pundarika (Kannada: ಪುಂಡರೀಕ), (Sanskrit: पुण्डरीक, romanized: Puṇḍarīka) was an Indian saint and a devotee of the Hindu deity Vithoba. Vithoba is a Vaishnava deity, considered a reincarnation of Vishnu. Pundalik is believed to have brought Vithoba to Pandharpur, where the deity's main shrine stands today. He is also regarded as the historical founder of the Varkari sect, which is centered on the worship of Vithoba.

Pundalik was one of the earliest practitioners of Kundalini Yoga. As he was considered a master of Kundalini Yoga, people used to call him "Kundalik." Over time, the name evolved into "Pundalik," symbolising Kundalini energy in the form of Vitthala (also known as Panduranga). Vitthala of Pandharpur is regarded as an incarnation of Vishnu. According to legends, Vitthala also represents the symbol of Kundalini energy. However, in Hinduism, this energy is believed to spiritually reside within all beings.

The brick on which Vitthala stands represents the Muladhara Chakra, the foundation of Kundalini energy. His hands, positioned like bows, symbolise the Ida and Pingala nadis, which intersect at the central channel of the body, known as the Sushumna or Brahma nadi. His body represents Purusha, signifying Vishnu or Krishna, while the tilaka (the mark on his forehead) represents the Ajna Chakra (also known as the Guru Chakra or Third-Eye Chakra). This subtle energy centre, believed to be located between the eyebrows along the spinal column, is mentioned by Krishna in the Bhagavad Gita.

Pundalik is a historical figure associated with the establishment and propagation of the Vithoba-centric Varkari sect. Ramakrishna Gopal Bhandarkar considers him the founder of the sect and the one who spread it in the Maratha region.

Frazer, Edwards, and P. R. Bhandarkar (1922) suggest that Pundalik attempted to unify the worship of Shiva and Vishnu, with this tradition originating in Karnataka. Ranade (1933) believes that Pundalik, a Kannada saint, was not only the founder of the Varkari tradition but also the first great devotee or high priest of the Pandharpur temple. Upadhyaya supports the priest theory but rejects the idea of Pundalik’s Kannada origin.

Tulpule also accepts that Pundalik was the historical founder of the Varkari sect but refrains from assigning a specific date to him due to a "lack of authentic evidence." According to M. S. Mate, Pundalik played a key role in persuading the Hoysala king Vishnuvardhana to build the Pandharpur temple dedicated to Vishnu, placing him in the early 12th century.

Deleury (1960) believes that Pundalik was a mystic influenced by the Vaishnava Haridasa sect of Karnataka and that he brought a significant transformation in the worship of Vithoba. He not only founded the Varkari sect but was also the first to identify Vithoba with Vishnu. Pundalik's fame led to the renaming of Pandharpur as Paundrika-Kshetra—the sacred place of Pundalik.

Other scholars, such as Raeside (1965), Dhanpalvar (1972), and Vaudeville (1974), have questioned the historicity of Pundalik altogether, dismissing him as a mythical figure.
