俄克喜林库斯(又译：奥克西林库斯、奥斯莱卡、俄西林古；英语：Oxyrhynchus；希腊语： ὀξύρρυγχος ，“尖鼻子”；古埃及语:Pr-Medjed；科普特语:Pemdje；现代埃及阿拉伯语(Egyptian Arabic):el-Bahnasa )是古埃及时期的上埃及城市。位于开罗西南偏南约160公里，即今明亚省 (Al-Minya)境内，是重要的考古遗址。在二十世纪，俄克喜林库斯地区被不断发掘，因而发现大量纸莎草纸古文书。这些出土文书，追溯至托勒密和古罗马时期的埃及，其中包括有：米南德的剧作和早期基督教文书──多马福音的经文碎片。

Oxyrhynchus (/ɒksɪˈrɪŋkəs/; Greek:Ὀξύρρυγχος Oxýrrhynkhos; "sharp-nosed"; ancient Egyptian Pr-Medjed; Coptic Pemdje; modern Egyptian Arabic el-Bahnasa) is a city in Upper Egypt, located about 160 km south-southwest of Cairo, in the governorate of Al Minya. It is also an archaeological site, considered one of the most important ever discovered. For the past century, the area around Oxyrhynchus has been continually excavated, yielding an enormous collection of papyrus texts dating from the time of the Ptolemaic and Roman periods of Egyptian history. Among the texts discovered at Oxyrhynchus are plays of Menander, fragments from the Gospel of Thomas, and fragments from Euclid's Elements.
