A urine sample collection device having a collection vessel for capturing urine from a patient, and an associated sample collection container portion for gathering the urine sample in an assured manner without the need for manual transfer. The urine sample collection device can be easily mounted inside a toilet bowl, so that the patient can deliver the urine stream to the toilet in the normal manner to produce the urine sample. The device avoids splashes of residual urine after the sample container is remove from the collection vessel, and a urine flow barrier shield for automatically accommodating the clean-catch method for delivering a urine sample.
