茶壶是一种供泡茶和斟茶用的带嘴器皿，由壶盖、壶身、壶底和圈足四部分所组成。茶壶大小的选择可依照饮茶人数多寡而定，同时也需要视乎所冲泡茶种的特性，潮州的工夫茶所使用的茶壶就是比较小巧。茶壶的造型除了一般的桔子型，亦有瓜形、柿形、菱形、鼓形、六角形等，壶面的装饰花纹亦变化万千。材质方面，有瓷质、陶质、玻璃、铸铁及纯银等，陶质又以紫砂陶为佳。

选购茶壶除了外观美感的因素外，出水是否流畅挺直亦必须考虑。此外，用手指压住壶盖上的小孔后，再试将壶内的水倾倒，茶壶必须滴水不漏才显示壶盖与壶身的密合度良好。

A teapot is a vessel used for steeping tea leaves or an herbal mix in boiling or near-boiling water, and for serving the resulting infusion which is called tea. Dry tea is available either in tea bags or as loose tea, in which case a tea infuser or tea strainer may be of some assistance, either to hold the leaves as they steep or to catch the leaves inside the teapot when the tea is poured. Teapots usually have an opening with a lid at their top, where the dry tea and hot water are added, a handle for holding by hand and a spout through which the tea is served. Some teapots have a strainer built-in on the inner edge of the spout. A small air hole in the lid is often created to stop the spout from dripping and splashing when tea is poured. In modern times, a thermal cover called a tea cosy may be used to enhance the steeping process or to prevent the contents of the teapot from cooling too rapidly.
