Lutz Altepost (born October 6, 1981 in Emsdetten, North Rhine-Westphalia) is a German sprint canoeist who has competed since the late 1990s.

At the 1999 Junior World Championships in Zagreb, Croatia, he won two gold medals with Germany's four-man K-4 crew (K-4 500 m and K-4 1000 m).

As a senior, he has established himself among the elite K-1 500 m paddlers in international competitions but has yet to win an individual gold medal.

After the Athens Olympics Altepost was chosen to lead Germany's revamped K4 boat.

In their debut season together the new four won the K-4 1000 m world championship final in Zagreb ahead of reigning champions Slovakia giving Altepost his first gold medal as a senior.
