The part that attaches the rear derailleur to the frame somehow got badly bent on my ride home today. Looks like I am going to need to replace but I don't know what it is called to order the part. Is it easy enough just to buy one and replace?

its called “derailleur hanger” they are intended to bend so you don’t damage your frame
they are easily replaceable, and googling the model of your bike should lead you in a good direction of where to buy a new one.
Derailleur hanger. Yours happens to be replaceable. They are made to match a particular frame. You have to buy the exact replacement.
It’s pretty easy to replace, i broke it 2 times last winter, they snap pretty easily. Make sure to order the exact part though

Sometime you can bend them back if it’s not too far gone

Coincidence or not, I was having trouble setting it right today.

Some older bikes like my now busted Trek Navigator 50 have the derailer hanger permanently part of the frame. It can be bent back depending on the frame material. Mine got ran over. Just a bit of info in case you ever need it.
Derailleur hanger, also referred to as a mech hanger. It’s a sacrificial part which is deliberately designed to be weaker than both the frame and the Derailleur mechanism. In the event of an impact, it will bend or break rather than the frame or the Derailleur gear. Cheap and easy to replace, but there are loads of different types, so you need to take it off and take it to your local bike shop or look online to find the right one.

By the look of it, knackered….

You may be able to bend it back, or get an lbs to do it.
