Thursday October Christian II was a Pitcairn Islands political leader.

He spent several years on Norfolk Island but returned to Pitcairn in 1864.

He was the fifth Magistrate of the Pitcairn Islands, holding the office in 1844, 1851, 1864, 1867, 1873–1874, 1880 and 1882.

Everyone named Christian on Pitcairn is descended from him; a number of family branches, however, left Pitcairn permanently and settled on Norfolk Island.

Thursday October Christian II appears in Mark Twain's 1879 story "The Great Revolution in Pitcairn".
