   When I put
   <?php echo get_the_title($post->post_parent) ?>
   into my theme template the output is correct.

   However, if I try to put it into a function and then call it from functions.php it does not work. Are there some sort of global variables that I should be calling?

   I'm trying to use this with conditional parameters in the functions.php file because the template itself would get quite bloated if I had it inline.

   Thanks in advance for any help!

   Should be obvious, no? You are directly using the global variable $post (you're trying to access the $post->post_parent variable). So you need to put global $post; at the top of your function.

   function whatever()
   {
   global $post;
   echo get_the_title($post->post_parent);
   ...
