卷线器是一种用来钓青鱼、草鱼、鲢鱼、鳙鱼或海钓的工具，小鱼不需要使用卷线器。

唐朝、宋朝时期的唐人、宋人钓鱼就使用线轮，它是卷线器的前身，主要材料是竹子、木。

近现代以来，卷线器常使用新材料，包括塑料、金属等。

A fishing reel is a cylindrical device attached to a fishing rod used in winding and stowing line.

Modern fishing reels usually have fittings aiding in casting for distance and accuracy, as well as retrieving line. Fishing reels are traditionally used in the recreational sport of angling and competitive casting. They are typically attached to a fishing rod, though some specialized reels are mounted directly to boat gunwales or transoms.
