苏铁目（学名：Cycadales）统称苏铁，是苏铁纲（Cycadopsida）中一个唯一目，共有3科，10至12属约305种，分布在全球的热带和亚热带地区。本科植物为常绿乔木或灌木，典型特征是茎粗壮，多数有羽状叶集生于茎干顶部，孢子叶球也生于茎顶部，为雌雄异株植物。苏铁类植物常会被误认为棕榈或蕨类植物。

由于多数生长在人迹罕见的热带森林中，最近25年才逐渐被人们发现越来越多的品种，可能尚有许多品种没有被人们发现。苏铁被发现横跨许多世界各地的亚热带和热带地区。苏铁在南美洲和中美洲有最多样性，其余分布在墨西哥，安的列斯群岛，美国东南部，澳大利亚，美拉尼西亚，密克罗尼西亚联邦，日本，中国，东南亚，印度，斯里兰卡，马达加斯加等地则至少有65 种。有些苏铁可以生存在半沙漠、气候恶劣、干旱、潮湿的热带雨林环境下。

Cycadales is an order of seed plants that includes all the extant Cycads. These plants typically have a stout and woody (ligneous) trunk with a crown of large, hard and stiff, evergreen leaves. They usually have pinnate leaves. The individual plants are either all male or all female (dioecious). Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long, with some specimens known to be as much as 1,000 years old. Because of the superficial resemblance, they are sometimes confused with and mistaken for palms or ferns, but are only distantly related to either.
