小米辣（学名：Capsicum frutescens）又名小米椒、鸡嘴椒、辣虎等，为茄科辣椒属的植物。分布在印度、欧洲、南美以及中国大陆的云南等地。

小米辣是低矮的灌木，最高可达两米。它们一开始像草，但是随着年龄的增长可以非常木质化。对于小米辣来说非常典型的是向上生长的花和果实。一根茎上有多颗花。花呈喇叭状，或者甚至筒状。花萼的端部呈齿形，与中国辣椒不同的是它的底部没有变粗的地方。花瓣白色或绿色。花瓣向外张开。花粉囊蓝色或紫色，偶尔黄色，雄蕊超出花粉囊至少1.5毫米。比起人工栽培的品种它的果实成熟的速度比较慢，容易掉落。果实成熟后一般变成红色。

Capsicum frutescens is a species of chili pepper that is sometimes considered to be part of the species Capsicum annuum. Pepper cultivars of Capsicum frutescens can be annual or short-lived perennial plants. Flowers are white with a greenish white or greenish yellow corolla, and are either insect- or self-pollinated. The plants' berries typically grow erect; ellipsoid-conical to lanceoloid shaped. They are usually very small and pungent, growing 10–20 millimetres (0.39–0.79 in) long and 3–7 millimetres (0.12–0.28 in) in diameter. Fruit typically grows a pale yellow and matures to a bright red, but can also be other colors. C. frutescens has a smaller variety of shapes compared to other Capsicum species, likely because of the lack of human selection. More recently, however, C. frutescens has been bred to produce ornamental strains, because of its large quantities of erect peppers growing in colorful ripening patterns.
