Powershell equivalent to unix `which` command?

Question

Does powershell have an equivalent to the which command found in most (if not all) unix shells?

There are a number of times I'd like to know the location of something I'm running from the command line. In unix I just do which <command> and it tells me. I can't find an equivalent in Powershell.
