The workshop ?Towards Future Research on Space Weather Drivers? brought together 120 heliophysicists from the international community. The workshop was held in the city of San Juan, Argentina, from 2 to 9 July 2019, with the kick-off of the meeting being marked by the total solar eclipse on 2 July. The total solar eclipse was visible within a band ≈ 200 km wide that spanned the contiguous Argentina and Chile from well into the Pacific Ocean up to the Atlantic coast. The workshop participants witnessed the event from the ?Valle Encantado?, a region about 115 km to the north of the meeting site. The marvelous view of the eclipsed Sun over the Andes mountains, encompassed by the amazing landscape, in which attendees were immersed, offered an unforgettable experience.The central goal of the meeting was to promote the discussion and exchange of new knowledge in the field of space weather, compelling for our modern technology-reliant society needs, from the point of view of the phenomena that modulate it from their origin in the Sun, through their evolution in the interplanetary medium, until their arrival to geospace. The topics addressed at the meeting included the latest findings on phenomena and structures affecting space weather, from the solar interior to the lower solar atmosphere, energy release in the low atmosphere, initiation and consequences of eruptive phenomena, coronal mass ejections (CMEs), solar energetic particles, radio emissions, and solar radiation variation of short time-scale; this added to coronal large-scale structuring and coupling with the solar wind, interplanetary space weather drivers, tools and simulations for predictions, and future missions and instrumentation with space weather applications. The importance of the topics discussed during the meeting envisions the advances for the improvement of space weather forecasts based on their drivers, provided by recent and upcoming cuttingedge space-based missions and new solar instrumentation that was designed to detect and probe solar and interplanetary phenomena, together with increasingly more realistic simulations. This is the motivation behind this Solar Physics Topical Collection (TC) of 21 articles that covers such a broad range of subjects of interest to a large portion of the scientific community.
