Lade (Old Norse: Hlaðir) is a community in Trondheim, Norway. It is situated north-east of Midtbyen and north of the community of Lademoen. Lade is located on a peninsula bordering the Trondheimsfjord, an important waterway dating to the Viking Age. It is the site of historic Lade estate (Lade gaard) and the site of Lade Church (Lade kirke) which dates from ca. 1190. 
Historically Lade estate in Trondheim (Lade Storgård i Trondheim) was the seat of the Jarls of Lade (Ladejarler) who ruled Trøndelag and Hålogaland. The Jarls of Lade were a dynasty of Norwegian rulers, influential from the 9th century to the 11th century. The Lade farm remained crown property until sometime in the Middle Ages when it was operated by the Bakke Abbey. The abbey was dissolved in 1537 in the course of the Reformation at which time the site became crown property.
The present farm buildings were erected in 1811 at the direction of Hilmar Meincke Krohg. The farm was purchased by the City of Trondheim in 1917. During the period 1922-1960, Norges Teachers College was in the buildings. Lade farm was acquired by the Reitan Group (Reitangruppen) in 1992. The buildings were restored and became their headquarters in 1995.
Today the area is dominated by suburban housing, superstores, industry and some recreational areas, and is zoned for high car access. Two secondary schools are located at Lade; Ladejarlen Secondary School and Ringve Secondary School. The latter is close to Ringve Museum and Ringve Botanical Garden. Other institutions located at Lade include the shopping centre City Lade and the Norwegian Geological Survey.
Lade is connected to Lademoen by the Nordland Line, but only two stations offer services to Lade; Haakon 7th Ave and Rotvoll. In 1958 Ladelinjen, a tramway, was built from Lade to Prinsen's Street, but the line was closed with the rest of the Trondheim Tramway in 1988, because the city of Trondheim city did not have adequate funding to keep it going. Some sections have not been removed and can still be seen.
Lade also has one of few beaches in Trondheim. Due to the nature and location of Lade, property and housing prices are known to be on average 20% higher than the rest of the city. The recent years Lade has become attractive to young people with a high and stable income so therefore you don't see many students or immigrants living here. A regular condo apartment can go for over 4 million Norwegian Kroner (NOK). And a villa with sea view can easily go for over 10 million NOK.
Lade have many local famous people living there. Per Ciljan Skjelbred (born 1987) is one of the new crop of successful young footballers. Skjelbred built his 10 million kroner villa there. But you also have the multi millionaires including members of the Reitan family (Reitan Group). Øyvind Christensen that also have their home address at Korsvika in Lade.
