If by badge you mean Gym badges, they:
- Help raise the stats of your Pokemon
- Make high-level Pokemon and traded Pokemon obey you
- Let you challenge the Elite Four (if you have all eight)
If you are talking about the Hidden Move "Strength", it is located at the top of the Lost Tower near Solaceon Town. One of the old women will give it to you. Also, you will need the Canalave Gym Badge as well.
I saw a question just like this, almost the same question, and im going to ask you this: Which Game?
In Diamond/Pearl/Platinum, to use Strength outside of battle, you'll need the Mine Badge. This is available from Byron, who specializes in Steel types. He is Canalave City's Gym Leader.
It depends on what game your talking about. Be more specific, but if it's diamond/pearl/platinum, it's the sixth, obtained by defeating the steel-type gym leader.
you need the mine badge which you get from Bryon from Canalave City.
The heat badge (4th gym)
The Mine Badge(#6).
The sixth (Byron)
The 8th Badge in Pokemon Diamond is called The Beacon Badge.
Strength, which let's you move boulders around
First of all, badges get you into the Pokemon league. The coal badge in paticular, lets you use HM rock smash outside of battle.

Strength, which let's you move boulders around
You don't need a badge to get strength but you need a badge to use strength and that badge is the rainbowbadge and that is the 4th one in celadon city.
== == == ==
You get HM strength in the lost tower, which can be found south of Solaceon Town. Talk to an old lady in the 5th floor and she'll give the HM strength. But be4 you can use it, you must have the sixth gym badge, the canalave badge. Hope this helps.
In Diamond, Badge 5 can be gotten by defeating Fantina in her Gym in Hearthome City.
