Available tokens in the Filter Section of Views
I don't see any way in the Views UI to do this, but you certainly can with a hook:

function YOURMODULE_views_pre_view(&amp;$view, &amp;$display_id, &amp;$args) {

  if ($view-&gt;name=='THE_VIEW_YOU_ARE_LOOKING_FOR' &amp;&amp; ($node=menu_get_object())) {

    $filters = $view-&gt;display_handler-&gt;get_option('filters');

    $filters['nid']['value']['value'] = $node-&gt;nid;

    $view-&gt;display_handler-&gt;override_option('filters', $filters);

  }

}


which would set the value in the node nid filter to that of the node nid the View is displayed on.
