I've got some LiPo 3.7v batteries coming my way and was wondering if they would be okay to power the raw pin of my Arduino Pro Mini 3.3v.  The LiPo battery will be around 4.2v fully charge, but not 100% sure if it will be enough for the Pro Mini's onboard regulator?

In theory the Pro Mini uses a low dropout regulator so you should be fine (the spec says "Input Voltage: 3.35 -12V").

The best way to find out is to try it and see!

Connect the battery to "RAW" and see how many volts appear at Vcc.

Thanks  smiley

Sounds positive (no pun intended!)  Just waiting for my LiPo charger, so when it comes I'll try it and update this thread.
