Answer in Brief
The president for the period commonly referenced as 2016 to 2020 was Donald Trump, who took office on January 20, 2017, and served one full term through January 20, 2021. The phrase 2016 to 2020 typically overlaps with the last year of Barack Obama’s second term (January 2009–January 2017) and the first three years of Donald Trump’s presidency (January 2017–January 2021). This guide clarifies the timeline, election context, and verified facts about the presidency during this span.
Clarifying the Timeframe: 2016 to 2020
When people refer to the years 2016–2020, they often mean the period from early 2016 through the end of 2020. In terms of U.S. presidencies:
- Barack Obama was president until January 20, 2017.
- Donald Trump was inaugurated on January 20, 2017 and served until January 20, 2021.
Therefore, the president for the bulk of the 2016–2020 window—specifically from January 2017 to January 2021—was Donald Trump. The only portion of this interval in which a different individual held the office was the first few months of 2016, under Barack Obama.
2016 Election and Inauguration Timeline
Understanding the exact timeline helps avoid confusion about who was president in 2016 versus who was president in 2017–2020.
| Date or Period | Event | Why It Matters |
|---|---|---|
| November 8, 2016 | General election held; Donald Trump elected president | Determined the next president, though inauguration had not yet occurred |
| January 20, 2017 | Inauguration of Donald Trump as 45th president | Marked the official start of his term |
| January 20, 2021 | End of Trump’s term; inauguration of Joe Biden | Concluded the presidential term that began in 2017 |
Voters cast ballots in November 2016, but the presidency changed hands on Inauguration Day in January 2017, which is why Barack Obama remained president for the first part of 2016 and Donald Trump became president starting in 2017.
Presidential Term and Tenure Details
Under the U.S. Constitution and the Twenty-Second Amendment, a president may serve up to two four-year terms. Donald Trump’s term ran from January 20, 2017, to January 20, 2021. During this period, he oversaw the federal government’s executive branch, signed or vetoed legislation, and directed foreign and domestic policy.

While this article focuses on identification and timeline, the following table summarizes notable policy domains addressed during Trump’s presidency:
| Attribute | Verified Detail | Source Type |

Notable Context and Common Points of Confusion
Because the phrase “who was the president in 2016 to 2020” spans an election cycle, it can blur whether the question refers to calendar years or actual presidential terms. Key clarifications include:
- For most of 2016, Barack Obama was the sitting president.
- From January 2017 through January 2021, Donald Trump was the president.
- The year 2020 includes the COVID-19 pandemic response, an election, and the transition that began after the election certification in early 2021.
Public discourse during 2016–2020 frequently referenced these overlapping periods, which can make simple identification ambiguous without a precise timeline.

Why Accurate Dates Matter for Historical Understanding
Correctly identifying the president from 2016 to 2020 matters for research, citations, and public understanding.
