Gather all ingredients. Preheat an air fryer to 400 degrees F (200 degrees C) according to manufacturer's instructions.
Pat chicken thighs dry with a paper towel; brush skins with olive oil. Place chicken thighs, skin-sides down, in a single layer on a plate.
Combine smoked paprika, garlic powder, salt, and black pepper in a bowl; sprinkle ½ evenly over thighs. Flip thighs over; evenly sprinkle with remaining ½ seasoning mixture. Place thighs, skin-sides up, in a single layer in the air fryer basket.
Cook in the preheated air fryer until thighs are brown and the juices run clear, about 18 minutes. An instant-read thermometer inserted into centers should read at least 165 degrees F (74 degrees C).
Serve and enjoy!
