Dragon 313 (November 2003) has a half-ogre template along with other half-monster templates. You could stick it to an orc to get a half-orc/half-ogre. But I advise against doing so since the template is somewhat broken IMHO. A half-orc/half-ogre would get a modifier of +12 to it's strength.
Here is a half-orc/half-ogre I wrote up for my own game world.
* +8 Str, -2 Dex, +2 Con, -2 Int, -2 Wis, -4 Cha.
* Large Size Giant
* Space/Reach 10 feet/10 feet
* Base Speed 40 feet.
* Darkvision 60 feet
* Racial Hit Dice: A half-orc/half-ogre starts out with two levels in Giant. These give him 2d8 hp, +1 BAB and the following base saving throw modifiers: Fort +3, Ref +0, Will +0.
* Racial Skills: A half-orc/half-ogre's Giant levels give him 5 × (2+ Int modifier, minimum 1) skill points. It's class skills are Climb, Listen and Spot.
* Racial feats: The Giant levels give the half-orc/half-ogre one feat.
* Weapon and Armor Proficiency: All half-orc/half-ogres are proficient in all simple and martial weapons, light and medium armor, and shields.
* +3 natural armor bonus
* Automatic Languages: Common, Giant, Orc. Bonus Languages: Goblin.
* Favored class: Barbarian.
* Level Adjustment: +2
