Sort of - they contain a compound that is broken down into Hydrogen Cyanide, a well known poison especially in old crime novels.
The compound is also found in bitter almonds and cherry pits. Your body will release cyanide while breaking it down.
Your body can also detoxify small amounts of cyanide, however if there is too much, it will bond to haemoglobin (the protein responsible for transporting oxygen around your body) similar to carbon monoxide (it can displace carbon monoxide as it bonds better).
It has been used as a potential cancer treatment, however it proved too poisonous (most treatments for cancer are a poison that will kill the cancer effectively but do little harm to you).
However, they contain so little of it and you'd need to chew the seeds well to release it (otherwise the seeds are likely to pass whole through your digestive system), so in practice, while they contain poison, they are harmless, similar to carbon dioxide, and also somewhat similar to oxygen (it high enough concentrations, above atmospheric pressure, it can kill, but you need it to live (you don't need cyanide)).

Apple seeds are toxic to rabbits and many animals. Apple seeds contain a cyanide compound -- this is what makes them poisonous.
The seeds of the apple are poisonus. The poison is cyanide. This is the same poison Hitler used to go suicide.
Apple seeds contain amygdalin, a substance that releases cyanide into the blood stream when chewed and digested. However, apple seeds in small amounts do not contain enough cyanide to cause harm. However, it is better to spit out seeds to avoid any potential issues.
A poisonous compound found in the seeds, bark, and leaves of the sugar apple (cherimoya) tree.
Yes, you can give a hamster a small piece of an apple, but you must make sure that there are no apple seeds. Apple seeds are extremely poisonous for hamsters and would most likely kill them.

Apple seeds are not poisonous to guinea pigs. I give apples with the seeds in to my guinea pigs everyday. However one must be careful as guinea pigs can choke easily on apple seeds. Please NEVER give guinea pigs ANY type of seeds because thy can choke on them. If you have been giving them seeds and nothing has happened that doesn't mean seeds are safe, it means you guinea pig has been very lucky. Ask any exotic or cavy savy vet.
The seeds are poisonous if ingested.
