Buddhist symbolism is the use of symbols (Pali: patīka) to represent certain aspects of the Buddha's Dhamma (teaching). Early Buddhist symbols which remain important today include the Dhamma wheel, the Indian lotus, the three jewels, Buddha footprint, and the Bodhi Tree.

Buddhism symbolism is intended to represent the key values of the Buddhist faith. The popularity of certain symbols has grown and changed over time as a result of the evolution of its followers' ideologies. Research has shown that the aesthetic perception of Buddhist symbols positively influenced perceived happiness and life satisfaction.

Anthropomorphic symbolism depicting the Buddha (as well as other figures) became very popular around the first century CE with the arts of Mathura and the Greco-Buddhist art of Gandhara. New symbols continued to develop into the medieval period, with Vajrayana Buddhism adopting further symbols such as the stylized double vajra. In the modern era, new symbols like the Buddhist flag were also adopted.

Many symbols are depicted in early Buddhist art. Many of these are ancient, pre-Buddhist and pan-Indian symbols of auspiciousness (mangala). According to Karlsson, Buddhists adopted these signs because "they were meaningful, important and well-known to the majority of the people in India." They also may have had apotropaic uses, and thus they "must have been a way for Buddhists to protect themselves, but also a way of popularizing and strengthening the Buddhist movement."

At its founding in 1952, the World Fellowship of Buddhists adopted two symbols to represent Buddhism. These were a traditional eight-spoked Dhamma wheel and the five-colored flag.

The earliest Buddhist art is from the Mauryan era (322 BCE – 184 BCE), there is little archeological evidence for pre-Mauryan period symbolism. Early Buddhist art (circa 2nd century BCE to 2nd century CE) is commonly (but not exclusively) aniconic (i.e. lacking an anthropomorphic image), and instead used various symbols to depict the Buddha. The best examples of this aniconic period symbolism can be found at sites like Sanchi, Amaravati, Bharhut, Bodhgaya and Sarnath. According to Karlsson, three specific signs, the Bodhi tree, the Dharma wheel, and the stupa, occur frequently at all these major sites and thus "the earliest Buddhist cult practice focused on these three objects".

Among the earliest and most common Buddhist symbols found in these early Buddhist sites are the stupa (and the relics therein), the Dharma wheel, the Bodhi Tree, the triratna (three jewels), the vajra seat, the lotus flower, and the Buddha footprint. Several animals are also widely depicted, such as elephants, lions, nāga and deer. Contemporary Buddhist art contains numerous symbols, including unique symbols not found in early Buddhism.^{[citation needed]}

Theravada Buddhist art is strongly influenced by the Indian Buddhist art styles like the Amaravati and Gupta styles. Thus, Theravada Buddhism retained most of the classic Indian Buddhist symbols such as the Dharma wheel, though in many cases, these symbols became more elaborately decorated with gold, jewels and other designs.
