'''RPL''' (an acronym for '''Reverse Polish Lisp''') is the onboard calculator language for the HP-28 and [[wp:HP 48 series|HP 48]] lines of graphing calculators. It is a stack language (not a [[Lisp]]-like language, as its name implies), tightly integrated with the calculator system, with many instructions similar to Forth.
 
It can natively handle unsigned integers (named ''binary inegersintegers''), floating-point numbers (named ''real numbers''), complex numbers, vectors and matrices (named ''arrays''), lists and algebraic expressions.
 
There are actually two languages with the name RPL: '''User RPL''' and '''System RPL'''. System RPL is used in implementing the operating system, and User RPL is the language users use to write programs on the calculator.
