Alpena Pass was founded in 1908 on top of a graveyard shortly after the Missouri and North Arkansas Railroad was built through Boone County. In the 1950s, the word "pass" was dropped from the name, thus creating the current name, Alpena.

At the time of the town's founding, the town of Carrollton was in decline. Many of the buildings of Carrollton were disassembled, moved and reassembled at Alpena Pass. MADtv's Rice and Beans Tour once came through the town, doing a tongue-in-cheek exposé about rural America. They encountered a seemingly drug-intoxicated woman and had an interview with the "mayor".

According to the United States Census Bureau, the town has a total area of 3.5 km (1.4 sq mi), all land.
