The bottom‐up functionalization of solid surfaces shows increasing importance for a wide range of interdisciplinary applications. Multidentate anchors with more than two contact points can bind to solid surfaces with strong chemisorption, well‐defined upright configuration, and tailored functionality. The surface functionalization using multidentate anchors with three (tripodal), four (quadripodal), or more binding points is summarized herein, with a focus on those beyond classical tripodal anchors. In particular, the molecular design on how to achieve multisite interaction between anchor and substrate and the introduction of functional groups to thin films are discussed. Dropping anchors: Multidentate anchors with more than two contact points bind to solid surfaces with strong chemisorption, well‐defined upright configuration, and tailored functionality. The surface functionalization with multidentate anchors with three (tripodal), four (quadripodal), or more binding sites is summarized.
