在许多领域中,不稳定是指一个可由其输出或内在状态描述的系统,其状态可能会不受限制的成长(有时会称为发散)。另一个对应的词是稳定,稳定有许多种定义,其中一种定义是指对系统施加一个小型的外扰,使系统离开一平衡状态,外扰去除后,系统会回到原来的平衡状态。

以右图为例:

系统除了稳定及不稳定,也可能处于其他的情形,例如系统不会发散也不会回到原平衡状态的边界稳定(例如一个平地上的球),或是其状态会形成某种特定循环的极限环。

在结构工程中,一个结构若承受了过重的负荷,结构就会不稳定。负荷若超过一定的上限,结构的变形会使应力变大,结构 会再进一步的变形,会产生挫曲或局部破坏,这类的研究称为结构稳定性
