The Denny Regrade is a neighborhood in Seattle, Washington, USA, that stretches north of the central business district to the grounds of Seattle Center. Its generally flat terrain was originally a steep hill, taken down as part of a mammoth construction project in the first decades of the 20th century. The neighborhood is named after that project. The northeastern portion of the Denny Regrade is sometimes known as the Denny Triangle, a term that has gained currency as this neighborhood has seen increasing development in the first decades of the 21st Century.
