Guan Tianpei (1781 - 26 February 1841) was a Chinese admiral of the Qing dynasty who served in the First Opium War. His Chinese title was "Commander-in-Chief of Naval Forces". In 1838, he established courteous relations with British Rear-Admiral Frederick Maitland. Guan fought in the First Battle of Chuenpi (1839), the Second Battle of Chuenpi (1841), and the Battle of the Bogue (1841). The British account described his death in the Anunghoy forts during the Battle of the Bogue on 26 February 1841 as follows:

Among these Chinese officers, the most distinguished and lamented was poor old Admiral Kwan, whose death excited much sympathy throughout the force; he fell by a bayonet wound in his breast, as he was meeting his enemy at the gate of Anunghoy, yielding up his brave spirit willingly to a soldier's death, when his life could only be preserved with the certainty of degradation. He was altogether a fine specimen of a gallant soldier, unwilling to yield when summoned to surrender because to yield would imply treason.

The following day, his body was claimed by his family and a salute of minute-guns was fired from HMS Blenheim in his honour.
