The invention relates to an olefin disproportionation catalyst. The catalyst mainly solves the problem that the existing catalyst has low disproportionation activity. The olefin disproportionation catalyst comprises, by weight, a) 0.01 to 10 parts of a phosphorus element or an oxide thereof, b) 1 to 20 parts of a rhenium element or an oxide thereof, and c) 60 to 99 parts of alumina. The catalyst well solves the problem and can be used for industrial production of an olefin disproportionation reaction. 本发明涉及种烯烃歧化催化剂，主要解决现有技术中存在的催化剂歧化活性低的问题。本发明通过采用种烯烃歧化催化剂，以重量份数计，包括以下组分：a)0.01～10份磷元素或其氧化物；b)1～20份铼元素或其氧化物；c)60～99份氧化铝的技术方案，较好地解决了该问题，可用于烯烃歧化反应的工业生产中。
