Polyamide　(PA)　membrane　is　extensively　used　in　various　membrane　separation　processes　due　to　its　easy　preparation,　high　selectivity　and　good　acid　-base　stability.　However,　the　PA　material　is　vulnerable　to　the　attack　of　free　chlorine　which　causes　PA　chlorination　degradation　and　eventually　damages　the　membrane　selectivity.　As　such,　developing　chlorine　-resistant　membrane　has　become　a　research　focus　in　membrane　technology　recently.　This　accelerates　the　emergence　of　a　large　number　of　novel　PA　membranes.　However,　reviews　on　this　aspect　are　quite　rare　to　date.　Thus,　providing　an　updated　critical　review　on　the　PA　-based　anti　-chlorine　membrane　is　highly　needed.　This　paper　aims　to　critically　review　the　recent　development　in　the　PA　chlorine　-resistant　membrane　designed　specially　via　the　modification　of　the　PA　selective　layer.　The　recent　advances　in　the　PA　anti　-chlorine　membranes　are　briefly　introduced　first.　The　mechanism　and　influential　factors　of　the　chlorination　of　PA　membrane　are　subsequently　presented.　The　strengths　and　limitations　of　the　recently　developed　PA　anti　-chlorine　membrane　are　critically　evaluated　afterward.　The　challenges　and　future　research　directions　of　the　sustainably　chlorine　-resistant　PA　membranes　are　finally　discussed.　This　article　can　provide　insightful　guidance　for　the　future　development　of　the　PA　-based　chlorine　-resistant　membrane.
