Papyrus Oxyrhynchus 1 (P. Oxy. 1) is a papyrus fragment of the logia of Jesus written in Greek (Logia Iesou). It was among the first of the Oxyrhynchus Papyri discovered by Grenfell and Hunt. It was discovered on the second day of excavation, 12 January 1897, in the garbage mounds in the Egyptian town of Oxyrhynchus. The fragment is dated to the early half of the 3rd century. Grenfell and Hunt originally dated the fragment between 150 and 300, but "probably not written much later than the year 200." It was later discovered to be the oldest manuscript of the Gospel of Thomas.
