Shukra (/ˈʃuːkrə/ SHOO-krə; Sanskrit: शुक्र, IAST: Śukra) is a Sanskrit word that means "clear" or "bright". It also has other meanings, such as the name of a sage who was the preceptor of the asuras and taught them the Vedas. In mythology and Hindu astrology, the word refers to the planet Venus, one of the Navagrahas.

In Hinduism, Shukra is one of the sons of Bhrigu, one of the Saptarshis. He was the guru of the asuras and is also referred to as Shukracharya or Asuracharya in various Hindu texts. In another account found in the Mahabharata, Shukra divided himself into two, one half became the fount of knowledge for the devas (gods) and the other half became the knowledge source of the asuras (demons). Shukra, in the Puranas, is blessed by Shiva with Sanjeevini Vidhya after performing tapas to propitiate Shiva. Sanjeevini Vidhya is the knowledge of raising the dead back to life, which he used from time to time to restore life to the asuras. Later, this knowledge was sought by the devas and was ultimately gained by them.

Vamana, the dwarf avatar of Vishnu, requests the asura king Mahabali for three steps of land. Mahabali acceded to the request and as was the practice, took up the kamandalu to pour water to symbolically signify the donation to Vamana. When Shukra, the asuras' guru, had realised Vamana's true identity, he tried to prevent the flow of water from the kamandalu by blocking the spout, Vamana pierced the spout with a stick, blinded Shukra.

Shukra's mother was Kavyamata, whilst Shukra's wives were the goddesses Urjasvati, Jayanti, and Sataparva. Sometimes, Urjjasvati and Jayanti are considered to be one goddess. With her, Shukra produced many children, including Queen Devayani. Sataparva was childless.

In the Mahabharata, Shukracharya is mentioned as one of the mentors of Bhishma, having taught him political science in his youth.

In classical Vedic astrology or Jyotisha, Shukra is considered to be among the Navagrahas (Nine planets) that influence the pattern of life on earth. Shukra represents women, beauty, wealth, luxury, and sex. According to classical astrological texts, a powerfully placed Shukra, aspected by benefic planets such as Jupiter, and in favourable signs and houses in the birth chart, ensures material well-being. Its beej mantra is "Om Draam Dreem Draum Sah Shukraya Namaha". It is associated with Friday, and the gem diamond. The classical shastras ordain that the best method to attain the blessings of Shukra is to respect the women in one’s life.

It is also popularly propitiated through Devi Aradhana or worshipping the goddess Lakshmi.

Shukra as a planet appears in various Hindu astronomical texts in Sanskrit, such as the 5th century Aryabhatiya by Aryabhatta, the 6th century Romaka by Latadeva and Panca Siddhantika by Varahamihira, the 7th century Khandakhadyaka by Brahmagupta and the 8th century Sisyadhivrddida by Lalla. These texts present Shukra as one of the planets and estimate the characteristics of the respective planetary motion. Other texts such as Surya Siddhanta dated to have been complete sometime between the 5th century and 10th century present their chapters on various planets with deity mythologies.
