Introduction
The night sky is full of magic and mystery, and Halloween is the perfect season to bring those cosmic vibes inside. You don’t need a dark-robed warlock or a dusty grimoire to sparkle your walls with celestial charm.
Whether you’re a stargazer, witch-core lover, or just someone who prefers moonlight over orange string lights, these DIY projects channel lunar energy, galaxy hues, and starry silhouettes into your home.
Let’s jump into 33 celestial Halloween wall art ideas that feel dreamy, spooky, and totally magical—all creative, budget‑friendly, and perfect for your own cosmic haunt.
1. Moon Phase Wall Collage
Ever wondered how to capture lunar magic in one frame?

It’s both minimalist and meaningful—especially if you choose constellations with personal resonance.
3. Galaxy Canvas Pour
What if your wall art looked like a nebula?
