Digambara (/dɪˈɡʌmbərə/; "sky-clad") is one of the two major schools of Jainism, the other being Śvetāmbara (white-clad). The Sanskrit word Digambara means "sky-clad", referring to their traditional monastic practice of neither possessing nor wearing any clothes. Nakedness was the ideal practice of lord Mahavira and his immediate followers. Mahavira emphasised the importance of nakedness for monks. It symbolizes complete detachment and is an ideal form of conduct. Mahavira believed that renouncing clothes made the body immune to external influences like heat and cold, increasing resilience. Without clothes, a monk would avoid the distractions of acquiring, maintaining, and washing garments, allowing him to focus on spiritual growth and self-discipline.

Digambara and Śvetāmbara traditions have had historical differences ranging from their dress code, their temples and iconography, attitude towards female monastics, their legends, and the texts they consider as important. Digambaras maintain that women cannot attain nirvana. However, Śvetāmbaras differ and maintain that women as well as eunuchs can attain nirvana, having more inclusivity.

Digambara monks believe in the virtue of non-attachment and non-possession of any material goods. Monks carry a community-owned picchi, which is a broom made of fallen peacock feathers for removing and thus saving the life of insects in their path or before they sit.

The Digambara literature can be traced only to the first millennium, with its oldest surviving sacred text being the mid-second century Ṣaṭkhaṅḍāgama ("Scripture in Six Parts") of Dharasena (the Moodabidri manuscripts). One of the most important scholar-monks of the Digambara tradition was Kundakunda.

Digambara Jain communities are currently found in most parts of India like Rajasthan, Uttar Pradesh, Delhi, Bihar, Jharkhand, Madhya Pradesh, Maharashtra, Karnataka and Tamil Nadu. According to Jeffery D. Long, a scholar of Hindu and Jain studies, less than one fifth of all Jains in India have a Digambara heritage.

According to Heinrich Zimmer, the word Digambara is a combination of two Sanskrit words: dik (दिक्) (space, sky) and ambara (अम्बर) (garment), referring to those whose garments are of the element that fills the four quarters of space.

The Digambaras and Śvetāmbara disagree on how the Digambara subtradition started in Jainism. According to Digambaras, they are the original followers of Mahavira and Śvetāmbara branched off later in the time of Bhadrabahu when their forecast twelve-year famine triggered their migration from central India. One group of Jain monks headed west and north towards Rajasthan], while the second group headed south towards Karnataka. The former became Śvetāmbara and retained their "heretic" beliefs and practices such as wearing "white clothes" they adopted there, say the Digambaras.

In contrast, according to Śvetāmbara, they are the original followers, and Digambaras arose 609 years after the death of Mahavira (about 1st century CE) because of an arrogant man named Sivabhuti who became a Jain monk in a fit of pique after a fight at home. However, according to Jinabhadra Gaṇi Kshamashramana, in his work Viśeṣāvaśyaka Bhāṣya, from which this account of the sect's creation is derived, he explicitly states that Sivabhuti was the eighth heretic who is regarded as the founder 'Bodiya ditthi' or Botika sect, also known as the Digambara sect. He is accused of starting the Digambara tradition with what Śvetāmbara call as "eight concealments", of rejecting Jain texts preserved by the Śvetāmbara tradition, and misunderstanding the Jain ideology including those related to nuns and clothes.
