Codex Macedoniensis or Macedonianus is a Greek uncial manuscript of the Gospels written on parchment. It is designated by Y or 034 in the Gregory-Aland numbering of New Testament manuscripts, and ε 073 in the von Soden numbering of New Testament manuscripts. Using the study of comparative writing styles (palaeography), it has been dated to the 9th century. The manuscript has several gaps. Historian William C. Braithwaite described the manuscript as "very carefully written."
