An airflow intrusive nasal relief and snoring stopping device is applied in an oral cavity. The oral cavity includes an oral opening, an upper tooth, a tongue, a palate and a uvula. The nasal relief and snoring stopping device includes a tooth accommodating member accommodating the upper tooth, and an airflow intrusive member between the uvula and the oral opening The tooth accommodating member includes a left tooth region and a right tooth region that are symmetrical. The airflow intrusive member connects the left tooth region and the right tooth region, and extends from the tooth accommodating member towards the palate. With the airflow intrusive member intruding the airflow inhaled through oral opening, soft tissues in the oral cavity are prevented from the effect of the airflow and hence from vibrations that may cause snoring, thereby improving symptoms of nose congestion and allergies.
