'''''Learning Perl''''', also known as the '''llama book''',<ref>{{cite book|last=Castro|first=Elizabeth|year=2001|publisher=[[Peachpit Press]]|title=Perl and CGI for the World Wide Web|page=314|isbn=978-0-201-73568-0|accessdate=June 23, 2011|url=https://books.google.com/books?id=PodQAAAAMAAJ&q=%22Learning+Perl%22+schwartz}}</ref> is a tutorial book for the [[Perl]] programming language, and is published by [[O'Reilly Media]]. The first edition (1993) was authored solely by [[Randal L. Schwartz]], and covered Perl 4. All subsequent editions have covered Perl 5. The second (1997) edition was coauthored with [[Tom Christiansen]] and the third (2001) edition was coauthored with Tom Phoenix. The fourth (2005), fifth (2008), sixth (2011), seventh (2016), and eighth (2021) editions were written by Schwartz, Phoenix, and [[brian d foy]]. According to the 5th edition of the book, previous editions have sold more than 500,000 copies.<ref>Learning Perl, 5th ed., p. 1</ref>

Unlike ''[[Programming Perl]]'', this book is aimed at computer programmers new to Perl. The publisher offers a complete set of code examples presented in the 3rd Edition book.<ref>{{Cite web|url=http://examples.oreilly.com/learnperl4/|title = Examples / Learning Perl 4th Edition}}</ref>

Schwartz selected the world of ''[[The Flintstones]]'' for the examples in this book, giving rise to the somewhat frequent use of ''Fred'' and ''Barney'' as [[metasyntactic variable]]s, rather than the classic [[Foobar|''foo'' and ''bar'']].
