A little late to the party - there are several applications that will do this. Some examine contrast on the image, others look at EXIF data. Photoshop will create a selection using Select Focus. Lot's of good information in the previous 3 pages of responses.

I just downloaded, installed and tried this plug-in... it's quite slow and doesn't work properly with my Canon 7D Mark II files (which it's supposedly compatible with).
I don't have time to try a re-install or fiddle around with it right now. Maybe later. I'll update, if I can get it to work. But for now it's a bust.

)Both my EM1 & EM5 mark2 will show the focus point on the LCD by pressing the info button. On another note I always tell the camera where to focus. I use small focus points. I never let the camera chose. Tried it a couple of times and was not impressed.

I have the LR plug in, but I can't see much benefit in using it. The highlighted area does not show the actual point of focus - merely which focus point was used. Absolutely useless if you recompose the image after locking the focus; in fact it's misleading if you think the red rectangle indicates the sharpest areas in the photograph.
I suppose if you are using a tripod, everything firmly fixed down, then the focus point should equal the point of focus and therefore the sharpest area in the image will lie with the red rectangle, but if I use a tripod then I expect the focus to be correct anyway.
"Focus mask" (see Dngallagher's link above) appears to search the image for the sharpest areas, perhaps in the same way that Photoshop "Select > Focus area" does, and this is a far more practical and informative tool.

Focus mask seems good but so little in focus, is it me?

Focus points on Nikon only show if the viewfinder was used to take the picture. If the picture was taken in live view, then no focus points will show. Live view uses contrast detection AF, the viewfinder uses phase detection AF method.

That could be how the focus mask LR plugin works, looking at contrast. seems to be worth adding.

I don't have LR, but the free software by Nikon, View NX2, does show a red box in the center of live view images. The focus point just can't be seen in the camera when reviewing images.

If you move the slider in tiny increments from left to right, more and more will be shown as "in focus". If "Automatic" is chosen, then PS appears to work to a standard (of its own).
I use it on any image that will be printed at a large size - if (on Auto) the select focus tool selects the whole image on a setting on 1 (one), then I know the photo is fairly good throughout as regards sharpness. On the other hand, if the whole image selection is at setting 3 or greater, I have to look more carefully at the sharpness of the image, moving the slider will give some good clues as to where to look. Depth of Field obviously plays a part in proceedings, the shallower DoF then the higher the setting of the Focus area tool will be. It's very subjective.

Linda, the software that came with both of my Nikon digitals would allow me to turn on the focus spot as an option.

This is the free plug in I use for focus points. Works very well;

The link is http://www.lightroomfocuspointsplugin.com/ , but it seems to be dead at the moment, at least for me getting to it.
It is a handy plugin, but it will only show what focus point was used, not necessarily where the camera actually focused - If you focus and recompose the software has no way of knowing where you focused, only what focus point the camera actually used.
You can also get a plugin for lightroom that will display a focus mask, showing what is actually in focus, which might prove more beneficial.
