Tiên Lữ [tiən˧˧:lɨʔɨ˧˥] is a rural district of Hưng Yên province in the Red River Delta region of Vietnam.

According to the 2021 statistical yearbook of the whole Hưng Yên province, Tiên Lữ rural district covers an area of 92 km2.

His temple was built in the 15th century and it is also recognized as a special cultural relic of the whole Tiên Lữ rural district.
