Monthly Notices of the Royal Astronomical Society (MNRAS) is one of the world's leading scientific journals in astronomy and astrophysics. It is published by Blackwell Publishing on behalf of the Royal Astronomical Society (RAS) but, despite its name, is neither monthly (there are 36 issues a year) nor does it carry the notices of the RAS.

Two sorts of article are carried by MNRAS: papers, which can be of any length, and letters, which are printed more quickly but are limited to five pages in length. Both sorts are made available online via Blackwell's OnlineEarly service before being published in paper form. Editorial control of the journal is exercised by the RAS through an editorial board of professional astronomers. As part of the editorial process, all articles are subject to peer review by an expert in the field.

The first issue of MNRAS came out on February 9 1827 (as Monthly Notices of the Astronomical Society of London) and it has been published continuously ever since. It took its current name from the second volumne, after the Astronomical Society of London became the RAS.
