Slateport Market
The Slateport Market is an open-air bazaar featuring items that can't be easily found anywhere else. The Slateport Markets have been in business since the creation of Slateport City itself as the clean water made the food abundant in the area, so a local market started to grow. The Slateport Markets are situated next to the ocean, so the scent of the salty sea seeps through the air. There is a place to buy Secret Base decorations, vitamins and fresh seaweed there.
Doll shop
There is a shopkeeper at the Slateport Market in the bottom-left corner that sells Dolls.
TM shop
There is another shopkeeper at the Slateport Market in the middle-right side that sells TMs. This shopkeeper only appears after the player obtains TM43 (Secret Power) on Route 111.
Energy Guru
After defeating the Elite Four, the Energy Guru will occasionally announce a sale on television, when he will sell everything at half price.
Additionally, the woman standing next to the Energy Guru will award the Pokémon in front of the player's party with an Effort Ribbon, provided that the Pokémon does not have the Ribbon already and the Pokémon has previously acquired 510 effort values.

Oceanic Museum
- Main article: Oceanic Museum
The Oceanic Museum is a large two-floored museum located in the eastern district of Slateport. The museum was built by Captain Stern to teach others of the ocean and the ocean floor. There is a $50 entrance fee which must be paid upon entry. The first floor contains information about the sea. There are seven exhibits, each with a different piece of information about the sea. On the western wing, there are experiments and displays involving Whirlpools, Waterfalls, buoyancy, and fossilization. While, on the eastern wing, there are displays and samples of ancient beach sand, and old sedimentary rocks, as well as fun facts about the sea. On the second floor, there are nine more exhibits, which include models of the Hoenn region and the ship S.S. Anne. The museum can be entered free of charge before Team Magma or Team Aqua leave, as the reception believes that the player is part of their group. However, it only works if he/she lacks the money needed for the $50 fee, which will prompt the receptionist to believe that the player is part of either Team Magma or Team Aqua.
Pokémon Fan Club
- Main article: Pokémon Fan Club
Slateport is the home to the headquarters for the Hoenn branch of the Pokémon Fan Club. The Fan Club is basically a place for people to meet and chat about their favorite Pokémon and to show off their collections to each other. In general, the members are usually more oriented to unevolved, cute Pokémon and Pokémon Contests than Pokémon battles. The people in the Fan Club adore their Pokémon and give friendly advice. One of the women in the fan club will give away a Soothe Bell if the player's Pokémon has a high happiness. In Emerald, people show off their Pokémon in Contests because the Pokémon Contest hall in Lilycove City is too far to travel. The Hoenn Pokémon Fan Club Chairman sits in the center of the club house. He claims to have raised over 100 different Pokémon in his lifetime. He travels across the nation on his Fearow.

Tidal.
Name Rater
- Main article: Name Rater
The Name Rater of Hoenn lives in northern district of Slateport City. As always, he allows Trainers to change the nickname of any Pokémon they captured or received in-game. Those traded from outside sources will not be able to be renamed. If the Pokémon was caught by the player that currently owns it, he'll say that the name could be better and offer the player the option of changing it. If the Pokémon he's judging was obtained via a trade, he will say that the name is perfect and refuse to change it. However, if both players have identical Trainer IDs and secret IDs, he will allow name changes.
Pokémon Contest Hall
The Hyper Rank Pokémon Contest is located in Slateport. Only Pokémon who have beaten the Super Rank can perform here. It is replaced by the Battle Tent in Emerald.
