Short answer: Yes, many of them are—and they’re surprisingly popular. The most famous one is the prickly pear (from the Opuntia cactus). You’ve probably seen them in stores labeled as “cactus figs” or “tuna” (yes, that’s their Spanish name, not the fish).
But not all cactus fruits are safe to eat. Some are toxic, bitter, or just not worth the pain of getting poked. That’s why I’m here to help you avoid becoming a human pincushion.
The stars of the show: prickly pears
Prickly pears look like spiky, neon-green or purple ping-pong balls. Under that scary exterior—wait, let me be real: they’re covered in glochids, those tiny, invisible hairs that lodge in your skin like microscopic ninjas. (Pro tip: handle them with tongs or thick gloves. I learned the hard way.)
Slice one open, and you’ll find a juicy, jewel-toned flesh dotted with hard seeds. The taste? Like a watermelon crossed with a kiwi—sweet, floral, a little tart. You can eat it raw, or blend it into smoothies, cocktails, or jams. Yes, people make cactus jam. It’s surprisingly not weird.
What about other types?
Beyond prickly pears, there’s the dragon fruit (a.k.a. pitaya), which comes from a climbing cactus. You’ve seen it at the grocery store—it’s the one that looks like a pink art project with green scales. Inside, it’s mild, sweet, and full of tiny seeds.
Then there’s the saguaro fruit (from that iconic Arizona cactus). It’s edible but takes forever to harvest—and you need a permit to pick it. (The Tohono O’odham people traditionally used it to make syrup and wine. Talk about desert luxury.)

But here’s where it gets tricky
Some cacti produce fruits that are toxic or just taste like regret. For example, the Euphorbia cactus? Do not eat that. Its sap can burn your skin and mouth. Rule of thumb: unless you’re 100% sure it’s an Opuntia or Hylocereus (dragon fruit), don’t risk it.
Even with safe fruits, the skin is often inedible or covered in spines. So, no, you can’t just bite into a cactus like an apple. (Trust me, I’ve seen people try. It did not end well.)
