Parvati (Sanskrit: पार्वती, IAST: Pārvatī), also known as Uma (Sanskrit: उमा, IAST: Umā) and Gauri (Sanskrit: गौरी, IAST: Gaurī), is one of the principal goddesses in Hinduism, revered as the goddess of power, energy, nourishment, harmony, love, beauty, devotion, and motherhood. Along with Lakshmi and Sarasvati, she forms the trinity, known as the Tridevi.

From her first appearance as a goddess during the epic period (400 BCE – 400 CE), Parvati is primarily depicted as the consort of the god Shiva. According to various Puranas, Parvati is the reincarnation of Sati, Shiva's first wife, who relinquished her body to sever familial ties with her father, Daksha, after he had insulted Shiva. Parvati is often equated with the other goddesses such as Sati, Uma, Kali and Durga and due to this close connection, they are often treated as one and the same, with their stories frequently overlapping. In Hindu mythology, the birth of Parvati to the mountain lord Himavan and his wife Mena is primarily understood as a cosmic event meant to lure Shiva out of his ascetic withdrawal and into the realm of marriage and household life. As Shiva's wife, Parvati represents the life-affirming, creative force that complements Shiva's austere, world-denying nature, thus balancing the two poles of asceticism and householder life in Hindu philosophy. Parvati's role as wife and mother is central to her mythological persona, where she embodies the ideal of the devoted spouse who both supports and expands her husband's realm of influence. Parvati is also noted for her motherhood, being the mother of the prominent Hindu deities Ganesha and Kartikeya.

Philosophically, Parvati is regarded as Shiva’s shakti (divine energy or power), the personification of the creative force that sustains the cosmos. In this role, she becomes not only a mother and nurturer but also the embodiment of cosmic energy and fertility. She is the source of power that energises Shiva, who without her is incomplete. Parvati's mythology, therefore, is not just about her role as a wife but also about her cosmic function as the force that activates and sustains life. In various Shaiva traditions, Parvati is also regarded as a model devotee, and even viewed as the embodiment of Shiva's grace, playing a central role in the spiritual liberation of devotees. She is also one of the central deities in the goddess-oriented sect of Shaktism, where she is regarded as a benevolent aspect of Mahadevi, the supreme deity, and is closely associated with various manifestations of Mahadevi, including the ten Mahavidyas and the Navadurgas. Parvati is found extensively in ancient Puranic literature, and her statues and iconography are present in Hindu temples all over South Asia and Southeast Asia. In Hindu temples dedicated to her and Shiva, she is symbolically represented as the yoni.

Parvata (पर्वत) is one of the Sanskrit words for "mountain"; "Parvati" derives her name from being incarnated as the daughter of king Himavan (also called Himavata, Parvata) and mother Menavati. King Parvata is considered lord of the mountains and the personification of the Himalayas; Parvati implies "she of the mountain". Aparneshara Temple of Yama, Udhampur in the Indian Union Territory of Jammu and Kashmir is considered as the birthplace of Parvati and site of Shiva-Parvati Vivaha.

Parvati is known by many names in Hindu literature. Other names which associate her with mountains are Shailaja (Daughter of the mountains), Shailaputri (Daughter of Mountains), Haimavati (Daughter of Himavan), Maheshvari (Maheshvara’s wife), Girirajaputri (Daughter of king of the mountains) and Girija (Daughter of the mountains).

Shaktas consider the Parvati as an incarnation of Lalita Tripurasundari. Two of Parvati's most famous epithets are Uma and Aparna. The name Uma is used for Sati (Shiva's wife, who is the incarnation of Parvati) in earlier texts,^[which?] but in the Ramayana, it is used as a synonym for Parvati. In the Harivamsa, Parvati is referred to as Aparna ('One who took no sustenance') and then addressed as Uma, who was dissuaded by her mother from severe austerity by saying u mā ('oh, don't'). Uma also means that "the One born out of Om (The Pranava Mantra) She is also referred to as Ambika ('dear mother'), Shakti ('power'), Mataji ('revered mother'), Maheshwari ('great goddess'), Durga (invincible), Bhairavi ('ferocious'), Bhavani ('fertility and birthing'), Shivaradni ('Queen of Shiva'), Urvi or Renu, and many hundreds of others. Parvati is also the goddess of love and devotion, or Kamakshi (the goddess of fertility), abundance and food/nourishment, or Annapurna. She is also the ferocious Mahakali that wields a sword, wears a garland of severed heads, and protects her devotees and destroys all evil that plagues the world and its beings.

The apparent contradiction that Parvati is addressed as the golden one, Gauri, as well as the dark one, Kali or Shyama. As a calm and placid wife, Parvati is mentioned as Gauri, and as a goddess who destroys evil, she is Kali. Regional stories of Gauri suggest an alternate origin for Gauri's name and complexion. In parts of India, Gauri's skin color is golden or yellow in honor of her being the goddess of ripened corn/harvest and fertility.

Hymns such as Lalita Sahasranama give many epithets to the goddess based on the demons she had won over, such as:
