花盆（英语：flower pot），种花用的一种器皿，为口大底端小的倒圆台或倒棱台形状，质地多为泥、陶、瓷、塑料、玻璃、石及木制品，近年市场上还出现了利用可降解塑料聚乳酸PLA制成的环保花盆。塑料花盆材质有软性培养盆与硬式花盆两种。

花盆的底部通常有孔，以便让多余的水流出，防止植株根部因积水过多而生长不佳，甚至死亡，这样的花盆在室内往往会放在托盘上。随着人们生活质量的提高，也出现了底部完全密封的套盆，仅仅作为美观和装饰之用。植物可以通过根系随时利用到花盆里的水分。近来一些花盆加入了带有蓄水装置的自动灌溉系统。

A flowerpot, flower pot, or plant pot is a container in which flowers and other plants are cultivated and displayed. Historically, and still to a significant extent today, they are made from terracotta. Flowerpots are now often also made from plastic, wood, stone, or sometimes biodegradable material. An example of biodegradable pots are the so-called "Jiffy" pots. There are often holes in the bottom, to allow excess water to flow out, sometimes to a saucer that is placed under the flowerpot. The plant can use this water with its roots, as needed. Recently, some flowerpots have been made with an automatic watering system, using a reservoir.
