Kumhar or Kumbhar is a caste or community in India, Nepal, Bangladesh and Pakistan. Kumhars have historically been associated with the art of pottery.

The Kumhars derive their name from the Sanskrit word Kumbhakar meaning earthen-pot maker. Dravidian languages conform to the same meaning of the term Kumbhakar. The term Bhande, used to designate the Kumhar caste, also means pot. The potters of Amritsar are called Kulal or Kalal, the term used in Yajurveda to denote the potter class.

A section of Hindu Kumhars honorifically call themselves Prajapati after Vedic Prajapati, the Lord, who they believe created the universe.

According to a legend prevalent among Kumhars

Once Brahma divided sugarcane among his sons and each of them ate his share, but the Kumhara who was greatly absorbed in his work, forgot to eat. The piece which he had kept near his clay lump struck root and soon grew into a sugarcane plant. A few days later, when Brahma asked his sons for sugarcane, none of them could give it to him, excepting the Kumhara who offered a full plant. Brahma was pleased by the devotion of the potter to his work and awarded him the title Prajapati.

There is an opinion that this is because of their traditional creative skills of pottery, they are regarded as Prajapati.

The potters are classified into Hindu and Muslim cultural groups. Among Hindus, inclusion of artisan castes, such as potters, in the Shudra varna is indisputable. They are further divided into two groups-clean caste and unclean caste.

Among the Kumhars are groups such as the Gujrati Kumhar, Kurali ke Kumhar, Lad, Haral and Telangi. They all, bear these names after different cultural linguistic zones or caste groups but are termed as one caste cluster.
