The 3-Trails Crossing Memorial Highway is the official name for an interchange in south Kansas City, Missouri that was once considered one of Missouri's most congested locations. Although it is known as Grandview Triangle, it is not located in Grandview, a suburb of Kansas City. It is actually north of Grandview, still within the city limits of Kansas City. After several years of reconstruction, the interchange itself is largely congestion free during non-peak hours despite the high traffic on the highways approaching the interchange. During rush-hour moderate to major delays and numerous accidents are reported.

The name "Three Trails Crossing" refers to the Santa Fe, Oregon, and California Trails that cross there. It is a major interchange of five major highways in the Kansas City area: I-49, I-435, I-470, US 50, and US 71.
