Yes, you can iron cotton.

More Info: Cotton fabric garments readily wrinkle so ironing will likely be necessary.  The best way to iron cotton is to iron when the garment is still slightly damp and the wrinkles have not set in.  Turn the garment inside out and iron on a warm to high setting.  Cotton blends will require a lower heat setting. The garment's care label will take into consideration all blends and treatments and will usually offer ironing instructions.
