Scotts Seaplane Base (ICAO: KCDD, FAA LID: CDD) is a public use seaplane base located in the community of Crane Lake, in Saint Louis County, Minnesota, United States. It is privately owned by Darrell Scott and is also known at Scott's Seaplane Base.

Although most U.S. airports use the same three-letter location identifier for the FAA and IATA, Scotts Seaplane Base is assigned CDD by the FAA but has no designation from the IATA (which assigned CDD to Cauquira, Honduras).
