Vishvakarma or Vishvakarman (Sanskrit: विश्वकर्मा, lit. 'all maker', IAST: Viśvakarmā) is a craftsman deity and the divine architect of the devas in contemporary Hinduism. In the early texts, the craftsman deity was known as Tvastar and the word "Vishvakarma" was originally used as an epithet for any powerful deity. However, in many later traditions, Vishvakarma became the name of the craftsman god.

Vishvakarma crafted all of the chariots of the devas and weapons including the Vajra of the god Indra. Vishvakarma was related to the sun god Surya through his daughter Sanjna. According to the legend, when Sanjna left her house due to Surya's energy, Vishvakarma reduced the energy and created various other weapons using it. Vishvakarma also built various cities like Lanka, Dvaraka, and Indraprastha. According to the epic Ramayana, the vanara (forest-man or monkey) Nala was the son of Vishvakarma, created to aid the avatar Rama.

The term Visvakarman was originally used as an epithet for any supreme god and as an attribute of Indra and the Sun. The name Visvakarman occurs five times in the tenth book of the Rigveda. The two hymns of the Rigveda identify Visvakarman as all-seeing, and having eyes, faces, arms and feet on every side and he also has wings. Brahma, the god of creation, who is four-faced and four-armed resembles him in these aspects. He is represented as being the source of all prosperity, swift in his thoughts and titled a seer, priest, and lord of speech.

According to some parts of the Rigveda, Vishvakarma was the personification of ultimate reality, the abstract creative power inherent in deities, living and non-living being in this universe. He is considered to be the fifth monotheistic God concept: He is both The Architect and The Divine Engineer of The Universe from before the advent of time.

The later parts of the Rigveda reveal efforts to find a satisfactory answer to the mysteries regarding the origin of the Architect, the creation hymns present in these parts of the Rigveda mention individual creator gods as opposed to the collection of gods and their chiefs (Indra, Varuna, Agni, etc.) creating the architecture.

In the historical Vedic religion, the role of Vishvakarma as the builder of gods is attributed to Tvastar. Vedic Vishvakarman is identified with Prajapati rather than Tvaṣṭṛ. In later mythology, Vishvakarman is sometimes identified with Tvaṣṭṛ and is a craftsman deity.

In Vishnu Purana, Vishwakarma is identified as the son of Prabhasa, one of the eight Vasus and his wife Varastri, the sister of Brihaspati. In Mahabharata, he is named as the chief architect, constructing the celestial courts of the dikpalas in Swarga, as well as cities like Dwarka. In Ramayana, the city of Lanka is described as his creation, with its architect Nala being identified as his incarnation. He is also credited with construction of the vajra out of Dadhichi's bones and the Pushpaka vimana. One of his daughters, Samjna was married to Surya, but she fled away after being unable to bear Surya's rays. So Vishwakarma chiseled out 1/8th of Surya's sunshine, and with that he created various weapons such as the Sudarshan Chakra and the trishula. He is also credited with the creation of the apsara called Tilottama. In Skanda Purana, he is the sculptor who constructs the wooden image of Jagannath enshrined in Puri.

In the Brahmavaivarta Purana, Vishwakarma & Ghritachi are described to be the originator of the following artisan caste groups - florists (Mali in North India & Malakar in Bengal), conchshell workers (Shankhari in Bengal), weavers, goldsmiths, coppersmiths, ironsmiths (Panchal in Punjab, Lohar in North India, Karmakar in Bengal), carpenters (Tarkhan in Punjab, Khati in North India, Suthar in West India, Sutradhar in Bengal), stonemasons (Sompura Salat in Gujarat, Mistri in North India, Maharana in Odisha), potters and painters (Chitrakar in Nepal, Patua in Bengal), whose skills are credited to him. Five of these groups - carpenters, blacksmiths, goldsmiths, coppersmiths & stonemasons - are collectively called Viswakarma in South India.
