Penguin Readers is an ELT graded reader series for learners of English as a foreign language.

With carefully adapted text, new illustrations and language learning exercises, the print edition also includes instructions to access supporting material online. Titles include popular classics, exciting contemporary fiction, and thought-provoking non-fiction, introducing language learners to bestselling authors and compelling content. The eight levels of Penguin Readers follow the Common European Framework of Reference for language learning (CEFR).

Exercises at the back of each Reader help language learners to practise grammar, vocabulary, and key exam skills.

Before, during and after-reading questions test readers' story comprehension and develop vocabulary. The Puffin Keeper, a Level 2 Reader, is A1+ in the CEFR framework.

Sentences contain a maximum of two clauses, introducing the future tenses will and going to, present continuous for future meaning, and comparatives and superlatives.

It is well supported by illustrations, which appear on most pages.
