Six places in and around St. Louis that host birthday parties for little kids, with what each one’s own party page says: the starting price, how many kids it covers, how long you get and what’s included. Prices change and many add tax or fees, so treat them as a starting point. No one pays to be listed here.

No. We list places from their own party pages, and nobody pays for a spot or a better position.
Each listing comes from the venue’s or organizer’s own page and links to it. We only list a date, time or price when that page shows it, and anything we can’t confirm stays off. These were last checked Oct 21, 2026, and we recheck them every three months. How we choose and check.
One short email every Thursday evening with the best things to do with little ones in STL that weekend.
