{{for|a different family of polynomials B<sub>n</sub>''(''x'')'' occasionally called Bell polynomials|Touchard polynomials}}

In [[combinatorics|combinatorial]] [[mathematics]], the '''Bell polynomials''', named in honor of [[Eric Temple Bell]], are used in the study of set partitions. They are related to [[Stirling numbers|Stirling]] and [[Bell numbers]]. They also occur in many applications, such as in [[Faà di Bruno's formula]].
