LP Aquarii is a pulsating variable star in the constellation of Aquarius that varies between magnitudes 6.30 and 6.64. The position of the star near the ecliptic means it is subject to lunar occultations.
The star's variability was first detected in the Hipparcos satellite data, and it was given its variable star designation in 1999.
