I have a WPF ListBox control and I'm setting its ItemsSource to a collection of item objects. How can I bind the IsSelected property of the ListBoxItem to a Selected property of a corresponding item object without having an instance of the object to set as a Binding.Source?

Just override ItemContainerStyle:

   <ListBox ItemsSource="...">
     <ListBox.ItemContainerStyle>
      <Style TargetType="{x:Type ListBoxItem}">
        <Setter Property="IsSelected" Value="{Binding Selected}"/>
      </Style>
     </ListBox.ItemContainerStyle>
    </ListBox>
