Interlingua dictionaries are bilingual dictionaries intended to aid learners and speakers of the auxiliary language Interlingua. Some of the larger dictionaries are presented here.
The first Interlingua dictionary, titled Interlingua–English: A Dictionary of the International language, is often referred to as the Interlingua–English Dictionary (IED). First published in 1951, the IED still serves as an authoritative reference work, partly because its entries display the etymological connections between words which are often obscured in other languages. The IED was compiled by Alexander Gode and his research staff.
The 27,000 words of the IED are supplemented by the 25,000-word Supplementary List. While not a full dictionary, the list is a useful adjunct to the IED because many Interlingua words are identical, or nearly identical, to their counterparts in English. Thus, readers who speak English immediately recognize the Interlingua words and have no need for translations. Author Piet Cleij collects the entries during his work on Interlingua dictionaries.

Many Interlingua dictionaries are available online at the Babylon lingual website. In 2001, Panorama in Interlingua reported that Babylon was distributing the Interlingua–English Dictionary, by download or subscription, at an average rate of 846 issues a day.
