Assassin's Apprentice is the first book in the Farseer trilogy, originally published in 1995. The second and third books in the trilogy are Royal Assassin and Assassin's Quest respectively. This was the author's first book published under the pseudonym Robin Hobb. The working title for the book was Chivalry's Bastard and the contract for the trilogy was signed on 13th of July in 1993.  Assassin's Apprentice has been translated to over 20 languages. The Farseer trilogy has also been adapted into a series of graphic novels that is available in French and Dutch.
The dedication in this book is for several of Robin's cats:
Later (in the US at least from 1996, also in later UK edition) the dedication was changed to:
A note for collectors: The first two volumes of the Farseer trilogy were originally not released in hardback in the US, and all subsequent reprints were paperbacks until a limited edition hardcover set of the whole trilogy was published in December 2016 by Subterranean Press (see below). This immediately sold out.
The UK first edition hardback was limited in numbers but is still relatively easy to obtain second-hand. There have also been two more recent special editions from Voyager in hardback (which are standalone editions) as well as a 20th-anniversary hardcover slipcase edition for the whole trilogy (more below) .
- An American English trade paperback edition was issued in New York by Bantam Books in 1995 with ISBN 0553374451. The covers were illustrated by Michael Whelan. Original price $12.95.
- The Advance Reading Copy states the publication date of the paperback as April 17, 1995, while publication apparently was in May 1995.
- A British English hardcover edition was issued in London by Voyager/HarperCollins in 1995 with ISBN 0002246066, cover illustration by John Howe. The print run was about 2000 copies. The gold lettering on the cover of this edition is known to get more easily damaged than the in the rest of the series.
- The ARC for this book has a cover illustration by John Howe but it is completely different from the finished version, instead of a Red Ship it portrays Fitz with a dog. 250 - 500 copies were printed.
- A US paperback edition was issued in 1996 by Bantam Spectra with ISBN 055357339X, cover art by Michael Whelan (the same cover was used in reprints all the way to 2014).
- A UK paperback edition was issued in 1996 with ISBN 0006480098, cover art as in the hardback edition by John Howe.
- A UK paperback edition by Harper Voyager the 3rd of September 2007 market as "New Ed" with covers by Jackie Morris. This was the first in a series of "repackaged" Robin Hobb titles in the UK that included every book in the Farseer, Liveship Traders, Tawny Man and Soldier Son trilogies. ISBN 9780006480099, but it also comes up in searches with the old ISBN-10: 0006480098 which is the 1996 UK paperback. The stock image often seen online has a golden background similar to the 15th Anniversary Edition (see below) but in reality, the cover is bluish silver.
- A Voyager 15th Anniversary Edition in 2010 by HarperCollins/Voyager, hardcover with dust jacket and a marker ribbon and an introduction to Voyager from Publishing Director Jane Johnson. This is a standalone edition that was published alongside Raymond Feist’s Magician, Sara Douglass’ Battleaxe, George R. R. Martin’s A Game of Thrones and Kylie Chan’s White Tiger.  The cover art is the buck design by Jackie Morris used in the first UK paperback reprints, but with a golden background. ISBN?
- A new UK clothbound hardcover with ISBN 9780007491551 in March 2013 by Harper Voyager. This is a "standalone" edition that was part of a reprinting of "Voyager Classics". It was also packaged together as a set with Raymond E. Feist’s Magician with ISBN 9780007939381. The cover is the silhouette of a wolf on a lilac background.
- A new UK paperback edition on the 27 of March 2014 with new cover art by Jackie Morris, consisting of old style lettering and sigils, with ISBN 9780007562251. This new cover is part of a redesign of all the cover art of the Realm of the Elderlings books in the UK to match the design of the first UK edition of Fool's Assassin. This later Morris paperback design is the only one where you can collect a matching set of all the RotE books.
- A US paperback 2014/15 reprint edition with new cover art by Alejandro Colucci to match the US first edition design of Fool's Assassin. Uses the ISBN 9780553573398 which is essentially the same as in the original one.
- A World Book Night 2015 paperback edition with the second Jackie Morris cover art embedded on a white background. ISBN possibly 9780008135409?
- A UK slipcased hardcover edition by Harper Voyager the 22nd of October 2015 with ISBN 9780008115456, to mark the book's 20th anniversary. Includes new art by John Howe on the endpapers and an introduction from Robin Hobb and some friends. Matching volumes of the rest of the trilogy published later.
- A US hardcover edition by Subterranean Press in December 2016, with new cover art by John Howe. This is part of a reprint of the whole first trilogy and is available in three formats:

- An Illustrated Edition from DelRey books in the US, published on the 1st of October 2019 with ISBN 9781984817853. This is a hardcover edition featuring a new foreword from the author and 10 full-colour illustrations by Magali Villeneuve, to celebrate the 25th anniversary of the first publication. Also published in the UK by HarperVoyager on the 17th of October 2019 with ISBN 9780008363710. The US and UK editions feature the same artwork, but the texture of the cover is different, and whereas all the foil used in the US edition is golden, in the UK edition it is part copper, part silver. The UK edition also comes with a ribbon bookmark. There was also a misprint of 20 copies of the UK edition where the copper foil got replaced with blue.
- A 3 volume hardcover set of the Farseer trilogy by Folio Society the 3rd of September 2020. New introduction by the author, 5 full-page colour illustrations in each volume by David Palumbo and a redrawn double-page map by Neil Gower.
