Anyone have a good library or method for calculating among a list of lat/long polygons, which is closest to a single lat/long point?

I'm aiming to show users a list of regions sorted by their distance to their current location. I'm getting the lat/long coordinated natively from iOS & Android sdks, but looking for help on the distance calculation!
