Google Maps v3 Drag Polygon

It’s really not that hard. No need for one of the many diy scripts; just set the draggable property on your instance of google.maps.Polygon and you’re good to go.

Note: draggable was introduced in Google Maps v3.11 (dd 22 January 2013). The current stable version of Google Maps still is 3.10 however. For now (until 3.11 is the stable one), you can include the experimental 3.11 version by referencing

Here’s an example showing the Bermuda triangle

var map = new google.maps.Map(document.getElementById('map_canvas'), {
	zoom: 5,
	center: new google.maps.LatLng(24.886436490787712, -70.2685546875),
	mapTypeId: google.maps.MapTypeId.TERRAIN

var poly = new google.maps.Polygon({
	paths : [new google.maps.LatLng(25.774252, -80.190262), new google.maps.LatLng(18.466465, -66.118292), new google.maps.LatLng(32.321384, -64.75737), new google.maps.LatLng(25.774252, -80.190262)],
	strokeColor: '#ff0000',
	strokeOpacity: 1,
	strokeWeight: 1,
	fillColor: '#ff0000',
	fillOpacity: 0.4,
	draggable: true, // yes, it's that easy!
	geodesic: true // set to false if you do not want distortion due to the mercator projection
