The 26th Madras Native Infantry regiment was one of the most prominent infantry units of the erstwhile British Indian Army. The battalion was raised in the year 1794 under the British East India Company and remained in active service until 1922. It was a division of the Madras Native Infantry, which was a part of the Madras Army, before the start of the Indian Mutiny of 1857. The armed military forces of Madras Presidency were among of the 3 chief Presidency Armies in British India. The Madras Presidency Army was raised with the objective of protecting the commercial interests of the Honourable British East India Company. The military regiment was also incorporated as a part of the Madras Command. The Army of the British Presidencies functioned under the British East India Company until the Sepoy Mutiny of 1857. The Government of India Act 1858, authorized after the occurrence of the rebellion in the year 1857, relocated the control of the 3 Presidency Armies to the British Empire in India from the British East India Company.

Finally in the year 1903, the 3 separate British Indian Presidency Armies, namely the Madras Army, the Bengal Army and the Bombay Army, were amalgamated in order to form the United British Indian Army. The 26th Madras Native Infantry was also named as the 86th Carnatic Infantry regiment.
