After some poking around, I came up with

(defun diary-last-day (month year &optional mark)
  "Return the last day of the month.
Entry applies if date is the last day in MONTH, YEAR. The
constant t means all values.

An optional parameter MARK specifies a face or single-character
string to use when highlighting the day in the calendar."
  (let ((m (extract-calendar-month date))
        (y (extract-calendar-year date))
        (d (extract-calendar-day date)))
    (when (and 
           (or (eq month t)
               (= m month))
           (or (eq year t)
               (= y year))
           (= d (calendar-last-day-of-month m y)))
      (cons mark entry))))

Include %%(diary-last-day t t) Your Entry Here in your diary file. =)

There's probably a better way to do it out there..
