Khālsā (Punjabi: ਖ਼ਾਲਸਾ; [xaːlsaː])is the Eleventh and final temporal-Guru/leader of the Sikhs. It is the collective body of Singhs and Kaurs represented by the five beloved-ones. The Khalsa was inaugurated on March 30, 1699, by Guru Gobind Singh, the tenth Sikh Guru. The leadership was passed on by Guru Gobind Singh to the Khalsa and bestowed the title Guru Panth or Guru. Though, during the next nine years of his life, Guru Gobind Singh remained the Commander-in-chief of the Khalsa. It can be concluded the Khalsa is the Eleventh Guru of the Sikhs with Guru Granth Sahib its soul.

The Khalsa is also the nation of the sikhs. The Khalsa is responsibile for all executive, military and civil authority.

The meaning of Khalsa translates to "Sovereign/Free". Another interpretation is that of being 'Pure'. Guru Gobind Singh has declared the Khalsa as his true Guru and therefore as following described in the Sarbloh Granth the attributes of the Khalsa:

The Sikhs of the Khalsa can be identified with the given Five Ks and titles Singh and Kaur. This happens after being baptised to the order of the Khalsa. The tenth Sikh Guru, Guru Gobind Singh at an event which conincided with the Baisakhi day in year 1699 initiated that every Sikh must follow the Five Ks; they are not merely symbols but commitment to the faith and philosophy of Guru Nanak, Sikhism, and collectively form the external visible symbols; hence clearly and outwardly advertising and displaying one's commitment. It is as much analogous to the uniform of an organization, especially a Military.
