Which Tolkien character is also known as Strider?

Aragorn is the Tolkien character also known as Strider.

Strider is the name Aragorn uses while traveling as a ranger in the northern lands. He first appears under that identity at the Prancing Pony in Bree, where Frodo and his companions initially regard him with suspicion.

Aragorn’s hidden identity is central to The Lord of the Rings. He is the heir of Isildur and a descendant of the kings of Númenor, but he spends years protecting the people of Eriador rather than immediately claiming royal power. His lineage eventually becomes essential to the restoration of the kingdoms of Arnor and Gondor.

Strider is not a separate character or merely a nickname used by hobbits. It is one of several names and titles associated with Aragorn, including Elessar and King Elessar after his coronation.
