During the final year of his contract and approaching free agency in the 2016–17 season, Smith was traded to the New York Rangers in exchange for a third-round pick in the 2017 NHL Entry Draft and a second-round pick in the 2018 NHL Entry Draft on February 28, 2017.[6] Smith provided a stability to the Rangers blueline to finish the season with 4 points in 18 games.
On June 29, 2017, Smith agreed to forfeit his impending free agent status in signing to a four-year, $17.4 million contract to remain with the Rangers.[7] On Smith reportedly showed up to 2017 training camp out of shape, and the Rangers as a team struggled.

In the 2019–20 season, Smith played exclusively as a winger before switching back to defenceman permanently after the Rangers traded Brady Skjei.[11]
