Key Trump ally and the world's richest man Elon Musk has been vocal in his support of the AfD ahead of February's snap general election, prompting accusations of meddling from other political parties.
The AfD said its co-leader Tino Chrupalla had "accepted an invitation" to the January 20th event and would be accompanied by the party's deputy parliamentary group leader Beatrix von Storch.
Chrupalla said that the Trump presidency would "change the world for a long time" and that his party "stands ready to be a strong partner in Europe".
"Germany must maintain good and friendly relations with all countries," he added.
Chrupalla's colleague as co-leader and the AfD's top election candidate, Alice Weidel, appeared on a livestream with Musk last week on his X social network.

Before that Musk had posted that "only the AfD can save Germany" and wrote an opinion column in the Welt newspaper justifying his interventions.
CDU sends spokesperson
Germany's main centre-right opposition CDU/CSU, which is leading in opinion polls, will send its foreign affairs spokesman JĂĽrgen Hardt to the inauguration.
Hardt said it was important to "strengthen our relations with our most important non-European ally".
Hardt, also a member of the Bundestag, acknowledged concerns over Trump's stated aims to put tariffs on foreign goods and his scepticism of military aid to Ukraine.
But Hardt said "we can only find advantageous solutions for both sides through open dialogue", noting Trump's oft-expressed enthusiasm for striking a "good deal".
It is not customary for foreign leaders to attend US inauguration ceremonies and no political representatives from the current German government are expected to go.
Instead Germany will be officially represented by its ambassador in Washington, Andreas Michaelis.
Other prominent figures on the European far right have also said they are attending the inauguration, including Reform UK leader Nigel Farage and Eric Zemmour, head of France's Reconquest party.
