Ensign Arthur Marcus Hill Cheek (31 July 1840 – 16 June 1857) was an East India Company Officer known posthumously as "the young martyr of Allahabad."

Witnesses stated that Cheek refused to renounce his Christian faith during his captivity despite being held in stocks in the sun, in an attempt to encourage him to convert to Islam.

After taking leave for three weeks to visit family who were living in India Ensign Cheek made his way to his Regiment, arriving on 19 May.

The Officers of the 6th Bengal Native Infantry had full confidence in their men and around 80 members of that regiment formed the guard at Allahabad Fort.

He said that attempts were made by their captors to convert them from Christianity to Islam by keeping the prisoners in stocks in the sun without water until they capitulated.

He fell a victim to the wretched Indian Mutiny in 1857 and is memorable for his heroic conduct and faithful confession in his dying moments testified by the encouraging words which he then addressed to a native Christian catechist tormented by the Mohammedans "Come what may, do not deny the Lord Jesus."
