News of the move comes days before Trump is expected to describe changes he is making to his businesses to avoid potential conflicts of interest as the US president.
The Trump Organisation's general counsel, Alan Garten, described shutting down the four companies as routine "housecleaning," and said there is no existing Trump business venture in Saudi Arabia.
The four Saudi-related companies were among at least nine companies that Trump filed paperwork to dissolve or cancel since the election.
Trump's holdings include more than 500 private companies, some of which he creates for prospective deals. The complex and changing structure makes it difficult for Americans to track his financial interests and partners. Trump has disclosed the names and some details about companies in public filings.

But a complete picture of Trump's finances is unclear, given that he has broken with decades of presidential precedent by not releasing his tax returns.
Last year, Ivanka Trump singled out the Middle East and Saudi Arabia as potential locations.
During the campaign, he created eight companies that included Jeddah, a major Saudi city, in their formal names. Four of those companies were shut down months after they were created. The other four were dissolved about one week after the election.
Garten said yesterday that the dissolution of the companies, which occurred last month, was part of a periodic process to shed corporate entities that were no longer needed or were set up for ventures that did not materialize. Garten said he did not know why the companies were set up last year or whether they involved business ventures in Saudi Arabia that didn't happen.
