Below is a detailed tally of the results of the 2020 Republican Party presidential primary elections in the United States. In most U.S. states outside New Hampshire, votes for write-in candidates remain untallied.
Primary elections and caucuses can be binding or nonbinding in allocating delegates to the respective state delegations to the Republican National Convention. But the actual election of the delegates can be at a later date. Delegates are (1) elected at conventions, (2) from slates submitted by the candidates, (3) selected by the party's state chairman or (4) at committee meetings or (5) elected directly at the party's caucuses and primaries. Until the delegates are apportioned, the delegate numbers are by nature projections, but it is only in the states with nonbinding caucuses where they are not allocated at the primary or caucus date.
Several states decided to cancel their primaries and caucuses. They cited the fact that Republicans canceled several state primaries when George H. W. Bush and George W. Bush sought a second term in 1992 and 2004, respectively, and Democrats scrapped some of their primaries when Bill Clinton and Barack Obama were seeking reelection in 1996 and 2012, respectively. Hawaii was the only state among the cancelled races to officially appoint their pledged delegates immediately to incumbent President Donald Trump in 2019. Donald Trump's over 18 million votes he received in the Republican Primary is the most ever for an incumbent President in a primary.

## Overview of results
### Major candidates

The table below shows the four candidates that have either (a) held public office, (b) been included in a minimum of five independent national polls, or (c) received substantial media coverage. The president's challengers withdrew from the race after the primaries started, or in the case of De la Fuente, accepted one or more 3rd party nominations.
