Kripa (Sanskrit: कृप, lit. 'pity', IAST: Kṛpa), also known as Kripacharya (Sanskrit: कृपाचार्य, IAST: Kṛpācārya), is a figure in Hindu mythology. According to the epic Mahabharata, he was a council member of Kuru Kingdom and a teacher of the Pandava and Kaurava princes. He also a teacher of many warriors mentioned in the Mahabharata, including Karna.

Born to warrior-sage Sharadvan and apsara Janapadi in an extraordinary manner, Kripa and his twin-sister Kripi were adopted by King Shantanu of Kuru Kingdom. Kripa was trained by his birth father and became a great archer like him. Later in the epic, he fought on the Kauravas's side against the Pandavas in the Kurukshetra war and was among the three survivors on the Kaurava side, along with Ashwatthama and Kritavarma.

Kripa is a chiranjivi, an immortal being destined to live until the end of the Kali Yuga, the last yuga (age). According to some texts, he will also become one of the Saptarishi—the seven revered sages—in the next Manvantara, which is a cyclic period of time in Hindu cosmology.

The Sanskrit word Kripa (Kṛpa) means 'pity' or 'mercy'. According to the Mahabharata (c. 700 BCE – 400 CE), he and his sister were named "Kripa" and "Kripi" as they were adopted by King Shantanu out of pity. Kripa was given the title "acharya" ('master') as he was an expert archer.

In the epic, Kripa is known by many other names including Gautama ('descendant of Gautama'), Sharadvata ('son of Sharadvan'), Sharadvanputra ('son of Sharadvan') and Bharatacharya ('teacher of the descendants of Bharat').

According to the Adi Parva of the Mahabharata, a boy named Sharadvan was born to sage Gautama and his wife Ahalya. Contradictory to this account, some later Puranic scriptures such as Agni Purana mention him as Gautama's great-grandson. Sharadvan showed great passion in archery and as he matured, he became a great archer. He once did penance to become indomitable, but this threatened the devas, especially Indra. He then sent a beautiful apsara (celestial nymph), Janapadi, from heaven to distract the celibate saint. When Sharadvan saw her, he lost his control and ejaculated. Ashamed of his actions, he left his weapons and went deep into a forest. The semen fell on some weeds, dividing the weeds into two parts. A boy and a girl were born from the weeds.

Shantanu, the king of Kuru Kingdom, was hunting, when one of his soldiers spotted the twins and brought them to him. Shantanu became compassionate towards them that he adopted them and returned to his palace. The children were then named Kripa and Kripi. Sharadvan, who was performing tapas in the forest, heard of his children and went to the palace of Kuru. He revealed their identity to the king and taught Kripa the four branches of Dhanurveda (archery). Kripa became a great archer like his father and taught warfare to many warriors and kings.

The Adi Parva mentions that Kripa taught the Pandavas, Kauravas, Vrishnis and Yadavas about Dhanurveda. Later, the Pandava and Kaurava princes studied under Drona, Kripi's husband who was born to Bharadvaja and apsara Ghritachi in the similar way like her. When the princes' training was over, a test was organised. Karna—the adopted son of a charioteer—challenged Arjuna in an archery match, but Kripa interfered and asked Karna to specify his lineage.
