芜菁甘蓝（学名Brassica napobrassica），又名瑞典芜菁，是源自于卷心菜及芜菁的一种根茎类蔬菜。根可以有多种煮法，叶子当为叶菜类般食用。

芜菁甘蓝最早是由加斯柏·鲍欣（Gaspard Bauhin）于1620年所记载，提述它们在瑞典的野外生长。它们一般被认为是源自斯堪地那维亚或俄罗斯。有记录指早于1669年芜菁甘蓝就已经在英格兰的皇家花园出现。它们于1700年在法国出现。约翰·辛克莱尔爵士（Sir John Sinclair）指约于1781年至1782年间它们被引进到苏格兰，期后于1790年被广泛引进到英格兰。它们于19世纪初被带到北美洲，约于1817年在伊利诺伊州种植。

The rutabaga, swede (from Swedish turnip), turnip, or neep (Brassica napobrassica, or Brassica napus var. napobrassica, or Brassica napus subsp. rapifera) is a root vegetable that may have originated as a cross between the cabbage and the turnip. The roots are prepared for human food in a variety of ways, and the leaves can be eaten as a leaf vegetable. The roots and tops are also used as winter feed for livestock, when they may be fed directly, or by allowing the animals to forage the plants in the field.
