Abstract.Every polyharmonic function in a star domain has a representation given by Almansi [#!almansi!#]. Generalizing this representation, we introduce a class of functions called Almansi functions in an open set in ${\bf R}^n$, $n\geq 2$; and investigate their properties. In particular, every polyharmonic function in a star domain is an Almansi function.
