The Valley Trail is a 40-mile (64 km) route in Grand Teton National Park, Wyoming, running north from near Teton Village along the base of the Teton Range. It passes Phelps, Taggart, Bradley, Jenny, String, Leigh, Bearpaw and Trapper Lakes, and sections carry other names such as the Jenny Lake Trail or String Lake Trail. It can be reached at numerous trailheads in the park.

The trail's names come from the lakes it follows: the Jenny Lake Trail and String Lake Trail are simply the Valley Trail beside those two lakes. The southern end at Teton Village lies outside the park, so through-hikers pass a boundary marker rather than a gate.

The route is accessible year-round, but snowfall can block or make sections difficult in winter. Hikers should wear sturdy boots, carry plenty of water, and watch for wildlife, especially bears in the forested areas.

The trail's southern terminus sits near Teton Village, just outside the park boundary, so the route can be joined before entering Grand Teton. Along its 40 miles (64 km) it skirts the shores of eight lakes in order: Phelps, Taggart, Bradley, Jenny, String, Leigh, Bearpaw and Trapper. Sections carry their own names, such as the Jenny Lake Trail or the String Lake Trail.
