This study is focused on several aims Those are to figure out the features of vocabulary learning strategies made by the EFL students of Darussalam Islamic institute, to find the most strategy used by EFL students of Darussalam Islamic institute, the last is to know the least common vocabulary learning strategy made by EFL learners at Darussalam Islamic Institute.The study was carried out to 61 students as samples to collect the data. The majority of the respondent is female which is about 53 respondents and the rest is 8 male respondents from two classes in which each class consist of 30 students.The data collection involved several instruments, namely observation, questionnaire, and interview.

The researcher took and moved the results of the questionnaire from spreadsheet to Microsoft excel 2010, then analyzed the data to explore EFL vocabulary learning strategies by using Microsoft excel 2010 with the =average formula. the overall implication of vocabulary learning strategies indicated that the most strategy applied is a cognitive strategy which is preferably used strategy by EFL learners with the highest total average score among others 3.27. And the least vocabulary learning strategy used is social strategies with the average lowest total average score of 2.49.And the features shown by the respondebt are they tend to use a mechanical means. In which, those ways are taking a note in class for finding the new word in the teaching-learning process, writing word lists can facilitate the learners in vocabulary learning by sorting the vocabulary alphabetically. They also give characteristics like analyzing any available pictures and gestures and sometimes analyzing part of speech.
