2016–17 Scarlets season
The 2016–17 season was the 14th season in the history of the Scarlets, a Welsh rugby union regional side based in Llanelli, Carmarthenshire. In this season, they won the Pro12 playoffs after finishing third in the league, and also competed in the Rugby Champions Cup and the Anglo-Welsh Cup. It was Wales international centre Jonathan Davies' first season back at the region after leaving for Clermont Auvergne in 2014. Scarlets also signed Welsh international Rhys Patchell, South African international Werner Kruger and New Zealander Johnny McNicholl ahead of the 2016–17 season, whilst Welsh internationals Rhodri Jones and Rhodri Williams, club stalwart Phil John and New Zealand international Regan King were among the players who left.
