The Lemmenjoki ({{langx|fi|Lemmenjoki}}, {{langx|se|Leammi}}) is a river in the northern part of the Finnish province of Lapland. Some {{convert|80|km|mi}} long, it flows from Nautajänkä, via Lake Paatari, terminating in Lake Inari.{{Cite book |last=Bambaradeniya |first=Channa N.

The name of the river comes from the Sami word "Leammijohka", meaning "warm river" or "the river of love".{{Cite book |last1=Ranta |first1=Reetta |url=https://books.google.com/books?id=Sf3uEAAAQBAJ&dq=lemmenjoki+river&pg=PA235 |title=Back to Nature Finland: Explore nature, myths, and ancient wisdom |last2=Huttunen |first2=Antti |date=2024-01-16 |publisher=Power Animals United |isbn=978-952-69866-1-6 |language=en}} Due to an erroneous folk etymology, the form Lemmenjoki is often associated with the Finnish word lempi (genitive form lemmen), meaning "love".

The Lemmenjoki National Park derives its name from the river.
