Yep, check this out: http://jsfiddle.net/AlienWebguy/JU3xj/5/

Essentially, we first create a small plugin called scrollTo:

jQuery.fn.extend({
    scrollTo : function(speed, easing) {
        return this.each(function() {
            var targetOffset = $(this).offset().top;
            $('html,body').animate({scrollTop: targetOffset}, speed, easing);
        });
    }
});

Then, getting the html to scroll to that position in the DOM is very simple:

$('div.whatever').scrollTo(300,'linear');

In that code, 300 is the duration – the time it takes for the scroll to happen. The larger the number, the slower it goes. It’s in milliseconds, so 1000 would equal 1 second. linear is the easing. For other types of easing, I’d recommend including JQueryUI– have a look at their easing options.
