In MVC3, how to get the current action name?

Is there a way to use HttpContext or the View context to get the current action name?

I can get the controller name using

    var routeValues = HttpContext.Current.Request.RequestContext.RouteData.Values;

    if (routeValues != null) 
    {
        if (routeValues.ContainsKey("controller"))
        {
            controllerName = HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
        }
    }
}
