Dharmasthala(listen) (earlier known as Kuduma) is an Indian temple town on the banks of the Nethravathi River in the taluk of Belthangady of the Dakshina Kannada district in Karnataka, India.

The town is known for its centuries-old Dharmasthala Temple, devoted to the Hindu god Manjunatha. Some other temples and shrines are dedicated to Ammanavaru, Chandranath and the Dharma Daivas (guardian spirits of Dharma) — Kalarahu, Kalarkayi, Kumaraswamy and Kanyakumari. The temple is unusual, as it is a Hindu temple run by a Jain administration, and poojas are conducted by Hindu priests who follow the Vaishnava ideologies. Most Shiva temples are run by Shaivas as opposed to the Madhva Brahmins, devotees of Vishnu and his avatars. On average, the temple attracts around 2,000 pilgrims a day.

A local legend says that the Shiva Linga was brought to Dharmasthala by Annappa, who was believed to have worked for the Dharmasthala Heggade family. Annappa was thought to have installed the Shiva Linga after his master expressed interest in offering his services to Lord Shiva. The Shiva Linga, which was installed overnight by Annappa not far from the Heggade household, was alleged to be moved from the Kadri Temple; Annappa was said to have disappeared after this.

Around 800 years ago, Dharmasthala was known as Kuduma (ಕುಡುಮ) in Mallarmadi, then a village in Belthangady (ಬೆಳ್ತಂಗಡಿ). Here lived the Jain chieftain Birmanna Pergade and his wife Ammu Ballathi in a house called Nelliadi Beedu. Pergade and the local chieftains built several shrines and invited Brahmin priests to perform the rituals. These priests requested Pergade to install a Shivalinga beside the native Daivas. The Daivas then sent their vassal Annappa Swamy to procure the linga of Lord Manjunatheshwara (ಶ್ರೀ ಮಂಜುನಾಥೇಶ್ವರ ಸ್ವಾಮಿ) from Kadri, near Mangalore. Subsequently, the Manjunatha temple was built around the linga.

Around the 16th century, Shri Devaraja Heggade invited Shri Vadiraja Swami of Udupi to visit the place. The Swamiji gladly came but refused to accept Bhiksha (food offering) because the idol of Lord Manjunatha had not been consecrated according to the Vedic rites. Shri Heggade then requested the Swamiji to reconsecrate the Shiva Linga himself. Pleased by the observance of the Vedic rites and Heggade's charity to all, the Swamiji named the place Dharmasthala the abode of religion and charity. Thus, the roots of charity and religious tolerance established by the Pergades 800 years ago have been kept by 21 generations of the Heggade family of Tulu lineage (Heggade being a derivative from Tulu word Pergade).

Sri Manjunatheshwara Cultural and Research foundation, started by the Temple committee, is engaged in preserving ancient manuscripts and paintings. A museum of antique objects called "Manjusha Museum" has been established, and a car museum houses a rare collection of vintage cars.

Traditional folk arts like Yakshagana and ethnic crafts like Navalgund carpets and Kasturi embroidery are revived by Dr. Heggade. Shri Dharmasthala Manjunatheshwara Dharmothana Trust is engaged in renovation of temples across Karnataka and every year, a Sarva Dharma Sammelana (multi-religious meet) is held at Dharmasthala, where spiritual leaders from various faiths and schools participate.

In 1973, a statue of Lord Bahubali was carved out of a single rock and installed at Dharmasthala on a low hill near the Manjunatha Temple. It is about 39 feet (12 m) high, has a 13 feet high pedestal and weighs about 175 tonnes. This is one of the five stone statues of Bahubali in Karnataka.

One project in Dharmasthala is called the Shri Kshetra Dharmasthala Rural Development Project, (known as SKDRDP) which organizes activities for rural development. Its employees go to villages to make small groups called Shree Shakti Sangha and provide bank loans to group members for business. They ensure supply of drinking water to villages in summer.

To fight the dowry system and to cut unnecessary expenses involved in the celebration of marriages, Dr. Veerendra Heggade (ಡಾ|| ವೀರೇಂದ್ರ ಹೆಗ್ಗಡೆ) started free mass marriages in 1972. Annual mass marriages are held usually during April every year. As of 2013, 10,698 couples have been married in mass marriages arranged by the Dharmasthala Temple Committee. The expenses of the wedding dress, the mangalasutra and a wedding feast for a limited number of the couple's guests are borne by the Shri Kshetra.

The average number of pilgrims per day to the temple is about 10,000. Every one of the pilgrims who visits Shri Kshetra Dharmasthala is treated like an honored guest, irrespective of caste, creed, culture or status. The "Anna Dana" (Food Donation) is one of the impressive aspects of this place. Free food is provided to the devotees. The temple has modern machinery. It makes quality food continuously, throughout the day. The dining hall is known as "Annapurna".
