Does cream soda have caffeine? Almost always no. A&W Cream Soda, the one people ask about most, is caffeine free at 0 mg per 12 oz can, per Caffeine Informer and A&W's own maker, Keurig Dr Pepper. If you came here expecting cream soda to be a sneaky caffeine source, the honest answer is that most of them are not. There is one loud exception, and it is not the brand you would guess.
Why cream soda is usually caffeine free
Cream soda is a vanilla-forward flavor, not a cola or a "red" energy-style pop, so brands rarely bother adding caffeine. A&W Cream Soda used to carry 29 mg per 12 oz, but it was reformulated to caffeine free, and the current cans are labeled that way. The diet line follows suit. A&W Zero Sugar Cream Soda is 0 mg, down from the old diet version's 22 mg, per Caffeine Informer.
Barq's is the one that trips people up. Barq's Root Beer has caffeine, so folks assume the whole Barq's shelf does. It does not. Barq's Red Creme Soda is 0 mg and printed "caffeine free" right on the can, per Caffeine Informer. Same brand, different rule.
The exception is Big Red. It reads like a cream soda to a lot of drinkers, but it is a red creme soda with caffeine baked in: 34 mg per 12 oz, per Caffeine Informer. That is a little less than a can of Coke and enough to matter if you are handing one to a kid at dinner.
The pattern to remember is that caffeine in soda is a recipe choice, not a flavor rule. Colas and most citrus energy-style sodas add it on purpose. Vanilla cream sodas almost never do, and the big two, A&W and Barq's, have both landed on zero. When a cream-style soda does carry caffeine, it tends to be a regional or "red" brand that grew up alongside colas rather than in the root beer and cream soda lane.

Sources: Caffeine Informer and Keurig Dr Pepper product facts. Numbers are per 12 fl oz can. Formulas change, so if you drink a brand not on this list, read the ingredient panel for the word caffeine.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
The short version behind the counter
If someone at the bar asks whether cream soda will keep them up, the safe answer is no for A&W and Barq's, yes for Big Red. Cream soda is not a caffeine delivery system the way cola or Mountain Dew is. The vanilla family stays clean almost across the board. The word "red" on a can is a better caffeine warning sign than the word "cream," which is why Big Red and Barq's Red Creme land on opposite sides of this chart despite both being red.
One more thing worth flagging, because people mix these up. Caffeine free does not mean sugar free or calorie free. A regular cream soda is still a full-sugar drink even when it has zero caffeine, so if you are cutting caffeine for sleep, cream soda is a fine pick, but if you are watching sugar, reach for the zero sugar version. And formulas do get reworked, exactly like A&W's did, so the ingredient panel on the can you are actually holding always wins over any chart, including this one. If it does not list caffeine in the ingredients, it does not have it.
