The paper analyzes the adaptation of word-final consonant clusters in Russian loanwords in Dolgan. Discussed are all 54 cases contained in a database of 1169 loans; thus, the data can be perhaps considered nearly complete. It is found that one cluster is valid, seven are invalid, and for thirteen there is not enough data to permit conclusions. Apocope of the word-final consonant of the cluster was found to be the preferred method of adaptation, while epenthesis and paragoge are rarer than could be expected.
