Lattice gauge theory has long served as a reliable non-perturbative method to study the Standard Model in its strong regime, as well as models of new physics with strong dynamics from first principles. The formulation of quantum field theory on a discrete spacetime lattice was key to early understanding of renormalization, but modern applications most commonly involve the use of high-performance computing to calculate numerical results from first principles. Enjoying rapid developments in both theoretical methods and computing power, such studies, now available for a wealth of physical quantities of interest, provide essential inputs to experiments at the intensity, energy, and cosmic frontiers of research in high-energy physics. In particular, given the reliance of the experimental program on hadrons and nuclei as the medium to discover new physics, and with the introduction of new computing paradigms such as Artificial Intelligence and Quantum Computing, research in Lattice Gauge Theory in the U.S. will be more essential and more exciting than ever in the upcoming years. A number of research directions we envision the community of lattice gauge theorists to pursue vigorously over the next decade are enumerated in the following.
