Yes, a U.S. citizen can apply for a K-3 visa for their spouse, but only after filing Form I-130, Petition for Alien Relative, with USCIS.

A K-3 visa is available to shorten the waiting time for foreign spouses of U.S. citizens, but it requires both Form I-130 and Form I-129F to be filed.

A spouse entering on a K-3 visa is allowed to live in the U.S. and later complete adjustment of status when the immigrant petition is approved.
