纸板是一种纸类的通称。

多数类型的「纸板」均可回收。干净（即未被加上化学物涂层）的纸板通常值得回收，但与加工成本相比，回收后价值甚微。重用后的纸板可作工业或家居用，例如切碎后的纸板可作动物的寝室的舖垫。

Card stock, also called cover stock or pasteboard, is a paper stock that is thicker and more durable than normal writing or printing paper, but thinner and more flexible than other forms of paperboard.

Card stock is often used for business cards, postcards, playing cards, catalogue covers, scrapbooking, and other uses which require higher durability than regular paper. The texture is usually smooth, but can be textured, metallic, or glossy. When card stock is labeled as cover stock it often has a coated finish on one side or both sides (CS1 or CS2 - Coated one side, Coated 2 side) to produce a glossy look and smooth texture, especially in use for the printing of business cards and book covers.
